Restricted Subsidiary, such merger or consolidation or such Asset Acquisition;
provided that Indebtedness of such Person which is redeemed, defeased, retired

      SECTION 2.3  Registrar and Paying Agent.  The Company shall maintain an
                   ---------------------------
office or agency in the Borough of Manhattan, The City of New York and, if and
so long as the Notes are listed on the Luxembourg Stock Exchange and the rules
of such stock exchange so require, in Luxembourg, where (i) Global Notes may be
presented or surrendered for registration of transfer or for exchange
("Registrar"), (ii) Global Notes may be presented or surrendered for payment
- -----------
("Paying Agent") and (iii) notices and demands in respect of such Global Notes
- --------------
and this Indenture may be served. In the event that Definitive Notes are issued,
(x) Definitive Notes may be presented or surrendered for registration of
transfer or for exchange, (y) Definitive Notes may be presented or surrendered
for payment and (z) notices and demands in respect of the Definitive Notes and
this Indenture may be served at an office of the Registrar or the Paying Agent,
as applicable, in the Borough of Manhattan, The City of New York. The Registrar
shall keep a

                                       22


register of the Notes and of their transfer and exchange. The Company, upon
notice to the Trustee, may have one or more co-Registrars and one or more
additional Paying Agents. The term "Registrar" includes any co-Registrar and the
term "Paying Agent" includes any additional Paying Agent. The Company initially
appoints The Bank of New York as Registrar and Paying Agent until such time as
The Bank of New York has resigned or a successor has been appointed. The Company
may change any Registrar or Paying Agent without notice to any Holder. Payment
of principal will be made upon the surrender of Definitive Notes at the office
of the Paying Agent, including, if any, the Paying Agent in Luxembourg. In the
case of a transfer of a Definitive Note in part, upon surrender of the
Definitive Note to be transferred, a Definitive Note shall be issued to the
transferee in respect of the principal amount transferred and a Definitive Note
shall be issued to the transferor in respect of the balance of the principal
amount of the transferred Definitive Note at the office of any transfer agent,
including, if any, the transfer agent in Luxembourg.

      If the notes are listed on the Luxembourg Stock Exchange, the Company will
appoint Kredietbank S.A. Luxembourgeoise, or such other Person located in
Luxembourg, as an additional paying and transfer agent. Upon the issuance of
Definitive Notes, Holders will be able to receive principal and interest on the
Notes and will be able to transfer Definitive Notes at the Luxembourg office of
such paying and transfer agent, subject to the right of the Company to mail
payments in accordance with the terms of this Indenture.

       SECTION 2.4  Paying Agent To Hold Assets in Trust.  The Company shall
                    -------------------------------------
require each Paying Agent other than the Trustee to agree in writing that each
Paying Agent shall hold in trust for the benefit of Holders or the Trustee all
assets held by the Paying Agent for the payment of principal of, Additional
Amounts, if any, Liquidated Damages, if any, premium, if any, or interest on,
the Notes, and shall notify the Trustee of any Default by the Company in making
any such payment. The Company at any time may require a Paying Agent to
distribute all assets held by it to the Trustee and account for any assets
disbursed and the Trustee may at any time during the continuance of any payment
Default, upon written request to a Paying Agent, require such Paying Agent to
distribute all assets held by it to the Trustee and to account for any assets
distributed. Upon distribution to the Trustee of all assets that shall have been
delivered by the Company to the Paying Agent, the Paying Agent shall have no
further liability for such assets.

       SECTION 2.5  List of Holders.  The Trustee shall preserve in as current a
                    ----------------
form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders.  If the Trustee is not the Registrar, the
Company shall furnish to the Trustee before each Record Date and at such other
times as the Trustee may request in writing a list as of such date and in such
form as the Trustee may reasonably require of the names and addresses of
Holders, which list may be conclusively relied upon by the Trustee.

       SECTION 2.6  Book-Entry Provisions for Global Notes.  (a) The Global
                    --------------------------------------
Notes initially shall (i) be registered in the name of DTC or the nominee of
such depositary, (ii) be delivered to the Trustee as custodian for such
depositary and (iii) bear legends as set forth in Section 2.7(c) hereto.

                                       23


      (b) Restrictions on Transfer and Exchange of Global Notes.
          -----------------------------------------------------
Notwithstanding any other provisions of this Indenture, a Global Note may not be
transferred as a whole except by DTC to a nominee of DTC or by a nominee of DTC
to DTC or another successor of DTC or a nominee of such successor depositary.
Interests of beneficial owners in the Global Notes may be transferred or
exchanged for Definitive Notes in accordance with the rules and procedures of
DTC and the provisions of Section 2.7. All Global Notes shall be exchanged by
the Company (with authentication by the Trustee) for one or more Definitive
Notes, if (a) any of DTC, Euroclear and Cedel (i) has notified the Company that
it is unwilling or unable to continue as a clearing agency, or (in the case of
DTC) ceases to be a clearing agency registered under the Exchange Act and (ii) a
successor to DTC, Euroclear or Cedel, as the case may be, that (in the case of
DTC) is registered as a clearing agency under the Exchange Act, is not able to
be appointed by the Company within 90 days of such notification or (b) at any
time at the option of the Company. If an Event of Default occurs and is
continuing, the Company shall, at the request of the Holder thereof, exchange
all or part of a Global Note for one or more Definitive Notes (with
authentication by the Trustee); provided, however, that the principal amount at
maturity of such Definitive Notes and such Global Note after such exchange shall
be $1,000 or integral multiples thereof. Whenever all of a Global Note is
exchanged for one or more Definitive Notes, it shall be surrendered by the
Holder thereof to the Trustee for cancellation. Whenever a part of a Global Note
is exchanged for one or more Definitive Notes the Global Note shall be
surrendered by the Holder thereof to the Trustee who shall cause an adjustment
to be made to Schedule A of such Global Note such that the principal amount of
such Global Note will be equal to the portion of such Global Note not exchanged
and shall thereafter return such Global Note to such Holder. A Global Note may
not be exchanged for a Definitive Note other than as provided in this Section
2.6(b).

      (c) In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b) of this Section 2.6, the Global
Notes shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall upon written instructions from the
Company authenticate and make available for delivery, to each beneficial owner
in exchange for its beneficial interest in the Global Notes, an equal aggregate
principal amount of Definitive Notes of authorized denominations.

      (d) Any Definitive Note constituting a Rule 144A Note delivered in
exchange for an interest in a Global Note pursuant to paragraph (b) of this
Section 2.6 shall, except as otherwise provided by Section 2.8, bear the Private
Placement Legend.

       SECTION 2.7  Registration of Transfer and Exchange.  (a)  Notwithstanding
                    -------------------------------------
any provision to the contrary herein, so long as a Note remains outstanding,
transfers of beneficial interests in Global Notes or transfers of Definitive
Notes, in whole or in part, shall be made only in accordance with this Section
2.7.

      (b) Other Exchanges.  In the event that a Global Note is exchanged for
          ---------------
Definitive Notes in registered form without interest coupons, pursuant to
Section 2.6(b), or a Definitive Note is exchanged for a beneficial interest in a
Global Note, such Notes may be exchanged or transferred for one another only in
accordance with such procedures as are substantially

                                       24



consistent with the provisions of Sections 2.6 and 2.7 herein and as may be from
time to time adopted by the Company and the Trustee.

      (c) Private Placement Legend.  Each Note issued hereunder shall, upon
          ------------------------
issuance, bear the legend set forth herein and such legend shall not be removed
from such Note except as provided in the next sentence.  The legend required for
a Rule 144A Note may be removed from a Rule 144A Note if there is delivered to
the Company and the Trustee such satisfactory evidence, which may include an
opinion of independent counsel licensed to practice law in the State of New
York, as may be reasonably required by the Company and the Trustee, that neither
such legend nor the restrictions on transfer set forth therein are required to
ensure that transfers of such Note will not violate the registration
requirements of the Securities Act.  Upon provision of such satisfactory
evidence, the Trustee, at the direction of the Company, shall authenticate and
deliver in exchange for such Note another Note or Notes having an equal
aggregate principal amount that does not bear such legend.  If such a legend
required for a Rule 144A Note has been removed from a Rule 144A Note as provided
above, no other Note issued in exchange for all or any part of such Note shall
bear such legend, unless the Company has reasonable cause to believe that such
other Note is a "restricted security" within the meaning of Rule 144 and
instructs the Trustee to cause a legend to appear thereon.

      The Initial Notes shall bear the following legend (the "Private Placement
                                                              -----------------
Legend") on the face thereof:

     RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (I) PURSUANT TO CLAUSE (D)
     TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR
     OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND (II) IN EACH OF THE

     APPEARING ON THE OTHER SIDE OF THIS SECURITY IS COMPLETED AND DELIVERED BY
     THE TRANSFEROR TO THE TRUSTEE, THIS LEGEND WILL BE REMOVED UPON THE REQUEST
     OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

     THE SECURITIES MAY NOT BE OFFERED, SOLD, TRANSFERRED OR DELIVERED AS PART
     OF THEIR INITIAL DISTRIBUTION OR AT ANY TIME THEREAFTER, DIRECTLY OR
     INDIRECTLY, OTHER THAN TO (INVESTMENT) BANKS, PENSION FUNDS, INSURANCE

     LARGE ENTERPRISES, WHICH ARE ACTIVE ON A REGULAR AND PROFESSIONAL BASIS IN
     THE FINANCIAL MARKETS FOR THEIR OWN ACCOUNT.

      After Separation (as defined in the Unit Agreement), the Global Notes
shall also bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
     DEPOSITORY TRUST COMPANY ("DTC") TO THE COMPANY OR ITS AGENT FOR
                                ---

     PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
     INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE,
     BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR
     SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY
     SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET
     FORTH IN SECTION 2.6 OF THE INDENTURE DATED JULY 8, 1999 PURSUANT TO WHICH
     THEY WERE ISSUED.

      (d) General.  By its acceptance of any Note bearing the Private Placement
          -------
Legend, each Holder of such a Note acknowledges the restrictions on transfer of
such Note set forth in this Indenture and in the Private Placement Legend and
agrees that it will transfer such Note only as provided in this Indenture.

      The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Note (including any transfers between or among Agent Members or
beneficial owners of interest in any Global Note) other than to require delivery
of such certificates and other documentation or evidence as are expressly
required by, and to do so if and when expressly required by the terms of, this
Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof.

      Each Holder of a Security agrees to indemnify the Company and the Trustee
against any liability that may result from the transfer, exchange or assignment
of such Holder's Security in violation of any provision of this Indenture and/or
applicable United States Federal or state securities law.

      The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.6 or this Section 2.7.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Registrar.

      (e) Any Initial Notes which are presented to the Registrar for exchange
pursuant to the Exchange Offer shall be exchanged for Exchange Notes of equal
principal amount upon surrender to the Registrar or an exchange agent of the
Initial Notes to be exchanged; provided, however, that the Initial Notes so
surrendered for exchange shall be duly endorsed and accompanied by a letter of
transmittal or written instrument of transfer in form satisfactory to the
Company, the Trustee and the Registrar or an exchange agent duly executed by the
Holder thereof or his attorney who shall be duly authorized in writing to
execute such document. Whenever any Initial Notes are so surrendered for
exchange, the Company shall execute, and upon receipt of the Company Order
provided for in Section 2.2, the Trustee shall authenticate and deliver to the
Holder the same aggregate principal amount of Exchange Notes as those Initial
Notes that have been surrendered.

                                       27


      (f) Definitive Notes shall be transferable only upon the surrender of a
Definitive Note for registration of transfer.  When a Definitive Note is
presented to the Registrar or a co-registrar with a request to register a
transfer, the Registrar shall register the transfer as requested if its
requirements for such transfers are met.  When Definitive Notes are presented to
the Registrar or a co-registrar with a request to exchange them for an equal
principal amount of Definitive Notes of other denominations, the Registrar shall
make the exchange as requested if the same requirements are met.  To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Definitive Notes at the Registrar's or co-registrar's
request.

      (g) The Company shall not be required to make, and the Registrar need not
register transfers or exchanges of, Definitive Notes selected for redemption
(except, in the case of Definitive Notes to be redeemed in part, the portion
thereof not to be redeemed) or any Definitive Notes for a period of 15 days
before a selection of Definitive Notes to be redeemed.

      (h) Prior to the due presentation for registration of transfer of any
Note, the Company, the Trustee, the Paying Agent, the Registrar or any co-
registrar may deem and treat the Person in whose name a Note is registered as
the absolute owner of such Note for the purpose of receiving payment of
principal, interest, Additional Amounts, if any, or Liquidated Damages, if any,
on such Note and for all other purposes whatsoever, whether or not such Note is
overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar
or any co-registrar shall be affected by notice to the contrary.

      (i) The Company may require payment of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection with any transfer or
exchange pursuant to this Section 2.7 (other than in respect of an Exchange
Offer, except as otherwise provided in a Registration Rights Agreement).

      (j) All Notes issued upon any transfer or exchange pursuant to the terms
of this Indenture will evidence the same debt and will be entitled to the same
benefits under this Indenture as the Notes surrendered upon such transfer or
exchange.

      (k) Holders of Initial Notes (or holders of interests therein) and
prospective purchasers designated by such Holders (or holders of interests
therein) will have the right to obtain from the Company upon request by such
Holders (or holders of interests therein) or prospective purchasers, during any
period in which the Company is not subject to Section 13 or 15(d) of the
Exchange Act, or is exempt from reporting pursuant to 12g3-2(b) under the
Exchange Act, the information required by paragraph d(4)(i) of Rule 144A in
connection with any transfer or proposed transfer of such Notes.

       SECTION 2.8  Replacement Notes.  If a mutilated Definitive Note is
                    -----------------
surrendered to the Registrar, if a mutilated Global Note is surrendered to the
Company or if the Holder of a Note claims that such Note has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Note in such form as the Note being replaced if the
requirements of the Trustee, the Registrar and the Company are met.  If required
by the Trustee, the Registrar or the Company, such Holder must provide an
indemnity bond or other

                                       28


indemnity, sufficient in the judgment of the Company, the Registrar and the
Trustee, to protect the Company, the Registrar, the Trustee and any Agent from
any loss which any of them may suffer if a Note is replaced. The Company, the
Trustee and Registrar, may charge such Holder for its reasonable, out-of-pocket
expenses in replacing a Note, including reasonable fees and expenses of counsel.
Every replacement Note is an additional obligation of the Company.

       SECTION 2.9  Outstanding Notes.  Notes outstanding at any time are all
                    -----------------
the Notes that have been authenticated by the Trustee except those canceled by
it, those delivered to it for cancellation, those reductions in the Global Note
effected in accordance with the provisions hereof and those described in this
Section as not outstanding.  Subject to Section 2.10, a Note does not cease to
be outstanding because the Company or any of its Affiliates holds the Note.

      If a Note is replaced pursuant to Section 2.8 (other than a mutilated Note
surrendered for replacement), it ceases to be outstanding unless the Trustee
receives proof satisfactory to it that the replaced Note is held by a bona fide
                                                                      ---- ----
purchaser.  A mutilated Note ceases to be outstanding upon surrender of such
Note and replacement thereof pursuant to Section 2.8.

      If the principal amount of any Note is considered paid under Section 4.1
hereof, it ceases to be outstanding and interest, Additional Amounts, if any and
Liquidated Damages, if any, on it cease to accrue.

      If on a Redemption Date or the Maturity Date the Paying Agent holds cash
in U.S. dollars or Government Securities sufficient to pay all of the principal
and interest due on the Notes payable on that date, then on and after that date
such Notes cease to be outstanding and interest, Additional Amounts, if any, and
Liquidated Damages, if any, on such Notes cease to accrue.

       SECTION 2.10  Treasury Notes.  In determining whether the Holders of the
                     --------------
required principal amount of Notes have concurred in any direction, waiver or
consent, Notes owned by the Company or its Affiliates shall be disregarded,
except that, for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Notes that a
Trust Officer of the Trustee actually knows are so owned shall be disregarded.

      The Company shall notify the Trustee, in writing, when it or any of its
Affiliates repurchases or otherwise acquires Notes of the aggregate principal
amount of such Notes so repurchased or otherwise acquired.  The Trustee may
require an Officers' Certificate listing Notes owned by the Company, a
Subsidiary of the Company or an Affiliate of the Company.

       SECTION 2.11  Temporary Notes. Until permanent Definitive Notes are ready
                     ---------------
for delivery, the Company may prepare and the Trustee shall authenticate
temporary Definitive Notes upon receipt of a Company Order in the form of an
Officers' Certificate. The Officers' Certificate shall specify the amount of
temporary Definitive Notes to be authenticated and the date on which the
temporary Definitive Notes are to be authenticated. Temporary Definitive Notes
shall be substantially in the form of permanent Definitive Notes but may have
variations that the Company considers appropriate for temporary Definitive
Notes. Without unreasonable

                                       29


delay, the Company shall prepare and the Trustee shall authenticate upon receipt
of a Company Order pursuant to Section 2.2 permanent Definitive Notes in
exchange for temporary Definitive Notes.

       SECTION 2.12  Cancellation.  The Company at any time may deliver Notes to
                     ------------
the Trustee for cancellation. The Registrar and the Paying Agent shall forward
to the Trustee any Notes surrendered to them for transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel and, at the written direction of the
Company, shall dispose of (subject to the record retention requirements of the
Exchange Act) all Notes surrendered for transfer, exchange, payment or
cancellation; provided, however, that the Trustee may, but shall not be required
to, destroy such canceled Notes. Subject to Section 2.7, the Company may not
issue new Notes to replace Notes that it has paid or delivered to the Trustee
for cancellation. If the Company shall acquire any of the Notes, such
acquisition shall not operate as a redemption or satisfaction of the
Indebtedness represented by such Notes unless and until the same are surrendered
to the Trustee for cancellation pursuant to this Section 2.12.

       SECTION 2.13  Defaulted Interest. If the Company defaults in a payment of
                     ------------------
interest on the Notes, it shall pay the defaulted interest, plus (to the extent
lawful) any interest payable on the defaulted interest, to the Holder thereof on
a subsequent special record date, which date shall be the fifteenth day next
preceding the date fixed by the Company for the payment of defaulted interest.
The Company shall notify the Trustee and Paying Agent in writing of the amount
of defaulted interest proposed to be paid on each Note and the date of the
proposed payment (a "Default Interest Payment Date"), and at the same time the
                     -----------------------------
Company shall deposit with the Trustee or Paying Agent an amount of money equal
to the aggregate amount proposed to be paid in respect of such defaulted
interest or shall make arrangements satisfactory to the Trustee or Paying Agent
for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
defaulted interest as in this Section 2.13; provided, however, that in no event
shall the Company deposit monies proposed to be paid in respect of defaulted
interest later than 10:00 a.m. New York City time on the proposed Default
Interest Payment Date with respect to defaulted interest to be paid on the Note.
At least 15 days before the subsequent special record date, the Company shall
mail to each Holder, with a copy to the Trustee, a notice that states the
subsequent special record date, the payment date and the amount of defaulted
interest, and interest payable on such defaulted interest, if any, to be paid.

       SECTION 2.14  CUSIP, ISIN and Common Code Numbers. The Company in issuing
                    -----------------------------------
the Notes may use a "CUSIP", "ISIN" or "Common Code" number, and if so, the
Trustee shall use the CUSIP, ISIN and Common Code number in notices of
redemption or exchange as a convenience to Holders; provided, however, that any
such notice may state that no representation is made as to the correctness or
accuracy of the CUSIP, ISIN and Common Code number printed in the notice or on
the Notes, and that reliance may be placed only on the other identification
numbers printed on the Notes.  The Company shall promptly notify the Trustee of
any change in any CUSIP, ISIN or Common Code number.

                                       30


       SECTION 2.15  Deposit of Moneys.  Prior to 10:00 a.m. New York City time
                     -----------------
on each Interest Payment Date and Maturity Date, the Company shall have
deposited with the Paying Agent in immediately available funds money sufficient
to make cash payments, if any, due on such Interest Payment Date or Maturity
Date, as the case may be, on all Notes then outstanding.  Such payments shall be
made by the Company in a timely manner which permits the Paying Agent to remit
payment to the Holders on such Interest Payment Date or Maturity Date, as the
case may be.

       SECTION 2.16  Certain Matters Relating to Global Notes.  (a) Members of,
                     ----------------------------------------
or participants in, DTC ("Agent Members") shall have no rights under this
                          -------------
Indenture with respect to any Global Note held on their behalf by DTC or the
Trustee as its custodian, or under the Global Note, and DTC may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of the Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any
agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by DTC or impair, as
between DTC and its Agent Members, the operation of customary practices
governing the exercise of the rights of a Holder of any Note.

      (b) The Holder of any Global Note may grant proxies and otherwise
authorize any person, including DTC and its Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

                                  REDEMPTION
                                  ----------

       SECTION 3.1  Optional Redemption.  The Company may redeem all or any
                    -------------------
portion of the Notes, upon the terms and at the redemption prices set forth in
each of the Notes. Any redemption pursuant to this Section 3.1 shall be made
pursuant to the provisions of this Article III.

       SECTION 3.2  Notices to Trustee.  If the Company elects to redeem Initial
                    ------------------
Notes pursuant to Paragraphs 8 or 9 of such Notes or Exchange Notes pursuant to
Paragraphs 7 or 8 thereof, it shall notify the Trustee in writing of the
Redemption Date and the principal amount of Notes to be redeemed at least 15
days prior to the giving of the notice contemplated by Section 3.4 (or such
shorter period as the Trustee in its sole discretion shall determine).  The
Company shall give notice of redemption as required under the relevant paragraph
of the Notes pursuant to which such Notes are being redeemed.

       SECTION 3.3  Selection of Notes to Be Redeemed.  If less than all of the
                    ---------------------------------
Notes are to be redeemed at any time, selection of such Notes for redemption
will be made by the Trustee in compliance with the requirements of the principal
securities exchange, if any, on which such Notes are listed, or if such Notes
are not so listed or such exchange prescribes no method of selection, on a pro
rata basis, by lot or by such other method as the Trustee in its sole discretion
shall deem fair and appropriate (and in such manner as complies with applicable
legal

                                       31


and exchange requirements); provided, however, that no Note of $1,000 in
aggregate principal amount or less shall be redeemed in part. In the event of
partial redemption by lot, the particular Notes to be redeemed shall be
selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the Redemption Date by the Trustee from the outstanding Notes not
previously called for redemption.

       SECTION 3.4  Notice of Redemption.  At least 30 days but not more than 60
                    --------------------
days before a Redemption Date, the Company shall publish in a leading newspaper
having a general circulation in New York (which is expected to be The Wall
Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allegmeine Zeitung) (and, if and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
a newspaper having a general circulation in Luxembourg (which is expected to be
the Luxemburger Wort)) or in the case of Definitive Notes, mail to Holders by
first-class mail, postage prepaid, at their respective addresses as they appear
on the registration books of the Registrar.  At the Company's request made at
least 45 days before the Redemption Date (or such shorter period as the Trustee
in its sole discretion shall determine), the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense; provided,
however, that the Company shall deliver to the Trustee, an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in the following items.  Each notice for
redemption shall identify the Notes to be redeemed and shall state:

      (a)  the Redemption Date;

      (b)  the Redemption Prices and the amount of interest, if any, Additional
           Amounts, if any, and Liquidated Damages, if any, to be paid;

      (c)  the name and address of the Paying Agent;

      (d)  that Notes called for redemption must be surrendered to the Paying
           Agent to collect the Redemption Price plus accrued and unpaid
           interest, if any, Additional Amounts, if any, and Liquidated Damages,
           if any;

      (e)  that, unless the Company defaults in making the redemption payment,
           interest, Additional Amounts, if any, and Liquidated Damages, if any,
           on Notes called for redemption cease to accrue on and after the
           Redemption Date, and the only remaining right of the Holders of such
           Notes is to receive payment of the Redemption Price upon surrender to
           the Paying Agent of the Notes redeemed;

      (f)  (i) if any Global Note is being redeemed in part, the portion of the
           principal amount of such Note to be redeemed and that, after the
           Redemption Date, interest, Additional Amounts, if any, and Liquidated
           Damages, if any, shall cease to accrue on the portion called for
           redemption, and upon surrender of such Global Note, the Global Note
           with a notation on Schedule A thereof adjusting the principal amount
           thereof to be equal to the unredeemed portion, will be returned and
           (ii) if any Definitive Note is being redeemed in part, the portion of
           the principal amount of such Note to be redeemed, and that, after the

                                       32


           Redemption Date, upon surrender of such Definitive Note, a new
           Definitive Note or Notes in aggregate principal amount equal to the
           unredeemed portion thereof will be issued in the name of the Holder
           thereof, upon cancellation of the original Note;

      (g)  if fewer than all the Notes are to be redeemed, the identification of
           the particular Notes (or portion thereof) to be redeemed, as well as
           the aggregate principal amount of Notes to be redeemed and the
           aggregate principal amount of Notes to be outstanding after such
           partial redemption;

      (h)  the paragraph of the Notes pursuant to which the Notes are to be
           redeemed; and

      (i)  the CUSIP, ISIN or Common Code number, and that no representation is
           made as to the correctness or accuracy of the CUSIP, ISIN or Common
           Code number, if any, listed in such notice or printed on the Notes.

      SECTION 3.5  Effect of Notice of Redemption.  Once notice of redemption
                   ------------------------------
is given in accordance with Section 3.4, Notes called for redemption become due
and payable on the Redemption Date and at the Redemption Price plus accrued and
unpaid interest, if any, Additional Amounts, if any, and Liquidated Damages, if
any.  Upon surrender to the Trustee or Paying Agent, such Notes called for
redemption shall be paid at the Redemption Price (which shall include accrued
and unpaid interest thereon, if any, Additional Amounts, if any, and Liquidated
Damages, if any, to the Redemption Date), but installments of interest, the
maturity of which is on or prior to the Redemption Date, shall be payable to
Holders of record at the close of business on the relevant Record Dates.

      SECTION 3.6  Deposit of Redemption Price.  Prior to 10:00 a.m. New York
                   ---------------------------
City time on the Redemption Date, the Company shall deposit with the Paying
Agent cash in U.S. dollars sufficient to pay the Redemption Price plus accrued
and unpaid interest, if any, Additional Amounts, if any, and Liquidated Damages,
if any, of all Notes to be redeemed on that date.  The Paying Agent shall
promptly return to the Company any cash in U.S. dollars so deposited which is
not required for that purpose upon the written request of the Company.

      If the Company complies with the preceding paragraph, then, unless the
Company defaults in the payment of such Redemption Price plus accrued and unpaid
interest, if any, Additional Amounts, if any, and Liquidated Damages, if any,
interest, Additional Amounts and Liquidated Damages on the Notes to be redeemed
will cease to accrue on and after the applicable Redemption Date, whether or not
such Notes are presented for payment.  With respect to Definitive Notes, if a
Definitive Note is redeemed on or after an interest Record Date but on or prior
to the related Interest Payment Date, then any accrued and unpaid interest,
Additional Amounts, if any, and Liquidated Damages, if any, shall be paid to the
Person in whose name such Note was registered at the close of business on such
Record Date.  If any Note called for redemption shall not be so paid upon
surrender for redemption because of the failure of the Company to comply with
the preceding paragraph, interest, Additional Amounts, if any, and Liquidated
Damages, if any, shall be paid on the unpaid principal, from the redemption date
until such principal is paid, and to the extent lawful on any interest not paid
on such unpaid principal, in each case at the rate provided in the Notes and in
Section 4.1.

                                       33


       SECTION 3.7  Notes Redeemed in Part.  Upon surrender and cancellation of
                    ----------------------
a Definitive Note that is redeemed in part, the Company shall execute and the
Trustee shall authenticate for the Holder (at the Company's expense) a new
Definitive Note equal in principal amount to the unredeemed portion of the
Definitive Note surrendered and canceled; provided, however, that each such
Definitive Note shall be in a principal amount at maturity of $1,000 or an
integral multiple thereof.  Upon surrender of a Global Note that is redeemed in
part, the Paying Agent shall forward such Global Note to the Trustee who shall
make a notation on Schedule A thereof to reduce the principal amount of such
Global Note to an amount equal to the unredeemed portion of the Global Note
surrendered; provided, however, that each such Global Note shall be in a
principal amount at maturity of $1,000 or an integral multiple thereof.


                                  ARTICLE IV

                                   COVENANTS
                                   ---------

       SECTION 4.1  Payment of Notes.  (a)  The Company shall pay the principal,

premium, if any, interest, Additional Amounts, if any, and Liquidated Damages,
if any, on the Notes in the manner provided in such Notes and this Indenture.
An installment of principal of or interest on the Notes shall be considered paid

Bankruptcy Law) on overdue principal and on overdue installments of interest
(without regard to any applicable grace periods), on any Additional Amounts, and
on any Liquidated Damages, from time to time on demand at the rate borne by the
Notes plus 1.5% per annum.  Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

       SECTION 4.2  Maintenance of Office or Agency.  The Company shall maintain
                    -------------------------------

affiliate of the Trustee, Registrar or co-Registrar) required under Section 2.3
where Notes may be surrendered for registration of transfer or for exchange and
where notices and demands to or upon the Company in respect of the Notes and
this Indenture may be served.  The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 11.2.  The Company hereby initially
designates the office of Corporation Services Company, located at Two World
Trade Center, Suite 8746, New York, New York, 10048, as its office or agency in

additional paying and transfer agent.

not, and will not permit any Restricted Subsidiary to, directly or indirectly,

       (A) no Default or Event of Default shall have occurred and be continuing;

       (B) the Company could Incur at least C1.00 of additional Indebtedness
     under Section 4.4(a); and

       (C) the aggregate amount expended for all Restricted Payments (the
     amount so expended, if other than in cash, to be determined in good faith
     by the Board of Directors, whose determination shall be conclusive and

     immediately succeeding paragraph or (II) to Incur Indebtedness pursuant to
     clause (x) of paragraph (b) of Section 4.4, plus (3) the aggregate amount
     by which Indebtedness (other than any Indebtedness subordinated in right of
     payment to the Notes) of the Company or any Restricted Subsidiary is
     reduced on the Company's balance sheet upon the conversion or exchange
     (other than by a Subsidiary of the Company) subsequent to the Issue Date
     into Equity Interests (other than Redeemable Stock and less the amount of
     any cash, or the fair value of property, distributed by the Company or any

                                       35


     Subsidiary upon such conversion or exchange), plus (4) without duplication
     of any amount included in the calculation of Consolidated Net Income, in
     the case of repayment of, or return of capital with respect to, any

     Issue Date, an amount equal to the lesser of (x) the repayment of, or the
     return of capital with respect to such Investment and (y) the cost of such
     Investment, in either case less the cost of the disposition of such
     Investment and net of taxes.

      (b) The foregoing provisions of Section 4.3(a) shall not prohibit:  (i)
the payment of any dividend within 60 days after the date of declaration thereof
if, at said date of declaration, such payment would comply with the provisions
of this Indenture; (ii) the redemption, repurchase, defeasance or other

right of payment to the Notes including premium, if any, and accrued and unpaid
interest, with the proceeds of, or in exchange for, Indebtedness Incurred under
clause (iii) of paragraph Section 4.4(b); (iii) the repurchase, redemption or
other acquisition of Equity Interests in the Company in exchange for, or out of
the Net Cash Proceeds of, a substantially concurrent offering of Equity
Interests (other than Redeemable Stock and excluding any Equity Interests issued

aggregate C5.0 million in any fiscal year of the Company; (vi) Investments in
any Person (the primary business of which is related, ancillary or complementary

pursuant to this clause (vi) does not exceed the sum of (a) C25.0 million, plus
(b) the amount of Net Cash Proceeds received by the Company after the Issue Date
from the issuance and sale of its Equity Interests (other than Redeemable Stock

(c) the aggregate amount by which Indebtedness (other than any Indebtedness
subordinated in right of payment to the Notes) of the Company or any Restricted
Subsidiary is reduced on the Company's balance sheet upon the conversion or
exchange (other than by a Subsidiary of the Company) subsequent to the Issue
Date into Equity Interests (other than Redeemable Stock and less the amount of
any cash, or the fair value of property, distributed by the Company or any
Restricted Subsidiary upon such conversion or exchange); and (vii) Investments
acquired in exchange for Capital Stock (other than Redeemable Stock) of the

                                       36


       Each Restricted Payment permitted pursuant to the immediately preceding
paragraph (other than the Restricted Payments referred to in clauses (ii) and
(vii) thereof and the Net Cash Proceeds from any issuance of Equity Interests
referred to in clauses (iii) and (iv) thereof) shall be included in calculating
whether the conditions of clause (C) of Section 4.3(a) have been met with
respect to any subsequent Restricted Payments. In the event the proceeds of an
issuance of Equity Interests (other than Redeemable Stock and excluding any
Equity Interests issued in connection with the Offering) of the Company are used
for the redemption, repurchase or other acquisition of the Notes, then the Net
Cash Proceeds of such issuance shall be included in clause (C) of Section 4.3(a)
only to the extent such proceeds are not used for such redemption, repurchase or
other acquisition of the Notes.

       (c) Not later than the date of making any Restricted Payment, the Company
shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.3 were computed, which calculations may
be based upon the Company's latest available financial statements.  The Trustee
shall have no duty to recompute or recalculate or verify the accuracy of the
information set forth in such Officers' Certificate.

       SECTION 4.4  Limitation on Indebtedness.    (a)  The Company will not,
                    --------------------------
and will not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness; provided, however, that if no Default or Event of Default shall
have occurred and be continuing at the time, or would occur as a consequence of
the Incurrence of any such Indebtedness, the Company may Incur Indebtedness if
immediately thereafter the ratio of (i) the aggregate principal amount of
Indebtedness of the Company and its Restricted Subsidiaries on a consolidated
basis outstanding as of the Transaction Date to (ii) the pro forma Consolidated
Cash Flow for the preceding two full fiscal quarters multiplied by two,
determined on a pro forma basis as if any such Indebtedness had been Incurred
and the proceeds thereof had been applied at the beginning of such two fiscal
quarters, would be greater than zero and less than or equal to 6.0 to 1.

       (b) Notwithstanding the foregoing, (except for Indebtedness under
subsection (vii) below) the Company and (except for Indebtedness under
subsections (v), (vi), (x) and (xii) below) any Restricted Subsidiary may Incur
each and all of the following:

       (i)  Indebtedness (other than Acquired Indebtedness) in an aggregate
     principal amount at any one time outstanding not to exceed C100.0 million
     Incurred to finance the cost (provided that such Indebtedness is Incurred
     at any time on or before, or within 90 days following, the incurrence of
     such cost) (including the cost of design, development, construction,
     acquisition, transportation, installation or integration) of equipment,
     inventory or network assets used in the Permitted Business or Equity
     Interests of (A) a Restricted Subsidiary that owns principally such assets
     from a Person other than the Company or a Restricted Subsidiary of the
     Company or (B) any Person that is principally engaged in the Permitted
     Business, that would become a Restricted Subsidiary and owns principally
     such assets; provided that (x) any such Indebtedness of a Restricted
     Subsidiary must be Incurred under one or more Credit Facilities, under one
     or more Capitalized Leases or from the vendor of the equipment, inventory
     or network assets acquired with the proceeds of such Indebtedness, (y) the
     amount of such Indebtedness of the Company

                                       37


     or any Restricted Subsidiary may not exceed the Fair Market Value of the
     assets so acquired and (z) the amount of any such Indebtedness permitted to
     be Incurred to acquire Equity Interests pursuant to clauses (A) or (B)
     shall be reduced by the amount of any Acquired Indebtedness Incurred in
     such acquisition;

       (ii) Indebtedness of any Restricted Subsidiary owing to and held by the
     Company, Indebtedness of the Company owing to and held by any Restricted
     Subsidiary or Indebtedness of any Restricted Subsidiary owing to and held
     by any other Restricted Subsidiary; provided that any subsequent issuance
     or transfer of any Capital Stock or any other event which results in any
     such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
     subsequent transfer of such Indebtedness (other than to the Company or
     another Restricted Subsidiary) shall be deemed, in each case, to constitute
     the Incurrence of such Indebtedness not permitted by this clause (ii); and
     provided, further, that Indebtedness of the Company owing to and held by a
     Restricted Subsidiary must be unsecured and subordinated in right of
     payment to the Notes;

       (iii) Indebtedness issued in exchange for, or the net proceeds of which
     are used to refinance or refund, then outstanding Indebtedness of the
     Company or a Restricted Subsidiary, other than Indebtedness Incurred under
     clauses (ii), (iv), (vii), (viii), (x) and (xii) of this paragraph, and any
     refinancings thereof in an amount not to exceed the amount so refinanced or
     refunded (plus premiums, accrued interest, and reasonable fees and
     expenses); provided that such new Indebtedness shall only be permitted
     under this clause (iii) if (A) in case the Notes are refinanced in part or
     the Indebtedness to be refinanced or refunded is pari passu with the Notes,
     such new Indebtedness, by its terms or by the terms of any agreement or
     instrument pursuant to which such new Indebtedness is issued or remains
     outstanding, is expressly made pari passu with, or subordinate in right of
     payment to, the remaining Notes, (B) in case the Indebtedness to be
     refinanced is subordinated in right of payment to the Notes, such new
     Indebtedness, by its terms or by the terms of any agreement or instrument
     pursuant to which such new Indebtedness is issued or remains outstanding,
     is expressly made subordinate in right of payment to the Notes at least to
     the extent that the Indebtedness to be refinanced or refunded is
     subordinated to the Notes, (C) the Stated Maturity of such new
     Indebtedness, determined as of the date of Incurrence of such new
     Indebtedness, is no earlier than the Stated Maturity of the Indebtedness
     being refinanced or refunded and (D) such new Indebtedness, determined as
     of the date of Incurrence of such new Indebtedness, has a Weighted Average
     Life to Maturity which is not less than the remaining Weighted Average Life
     to Maturity of the Indebtedness to be refinanced or refunded; and provided
     further that in no event may Indebtedness of the Company be refinanced or
     refunded by means of any Indebtedness of any Restricted Subsidiary pursuant
     to this clause (iii);

       (iv) Indebtedness (A) in respect of performance, surety or appeal bonds
     or letters of credit supporting Trade Payables, in each case provided in
     the ordinary course of business, (B) under Currency Agreements and Interest
     Rate Agreements; provided that such agreements (x) are designed solely to
     protect the Company or the Restricted Subsidiary, as the case may be,

     and (y) do not increase the Indebtedness of the obligor outstanding at any

                                       38


     time other than as a result of fluctuations in foreign currency exchange
     rates or interest rates or by reason of fees, indemnities and compensation
     payable thereunder, and (C) arising from agreements providing for
     indemnification, adjustment of purchase price or similar obligations, or
     from Guarantees or letters of credit, bankers' acceptances, surety bonds or
     performance bonds securing any obligations of the Company or any of its
     Restricted Subsidiaries pursuant to such agreements, in any case Incurred
     in connection with the disposition of any business, assets or Restricted
     Subsidiary of the Company (other than Guarantees of Indebtedness Incurred
     for the purpose of financing such acquisition by the Person acquiring all
     or any portion of such business, assets or Restricted Subsidiary), in a
     principal amount not to exceed the gross proceeds actually received by the
     Company or any Restricted Subsidiary in connection with such disposition;

       (v)  Indebtedness, to the extent that the net proceeds thereof are
     promptly (A) used to repurchase Notes tendered in a Change of Control Offer
     or (B) deposited to defease all of the Notes as described in Sections 8.1,
     8.2 and 8.3;

       (vi) Indebtedness of the Company represented by the Notes;

       (vii) Indebtedness represented by a Guarantee of the Notes and Guarantees
     of other Indebtedness of the Company by a Restricted Subsidiary in each
     case permitted by and made in accordance with Section 4.17;

       (viii) Indebtedness under one or more Credit Facilities (which shall be
     in addition to any such Indebtedness incurred under one or more Credit
     Facilities under clause (b)(i) above), in an aggregate principal amount at
     any one time outstanding not to exceed the greater of (x) C50.0 million and
     (y) 80.0% of Eligible Accounts Receivable at such time;

       (ix) Acquired Indebtedness provided that the aggregate amount of such
     Acquired Indebtedness of the Person that is to become a Restricted
     Subsidiary, or to be merged or consolidated with or into the Company or any
     Restricted Subsidiary in the contemplated transaction, or to be assumed by
     the Company or a Restricted Subsidiary in connection with an Asset
     Acquisition, outstanding at the time of such transaction does not exceed
     the Fair Market Value of the equipment, inventory, network assets and Cash
     Equivalents of any Restricted Subsidiary so acquired or that are acquired
     in such Asset Acquisition, as the case may be;

       (x)  Indebtedness of the Company not to exceed, at any one time
     outstanding, the sum of:

            (A) 2.00 times the Net Cash Proceeds received from the issuance
       and sale, other than to a Subsidiary, of Equity Interests (other than
       Redeemable Stock and excluding any Equity Interests issued in connection
       with the Offering) of the Company, less, (I) the amount of such proceeds
       used to make Restricted Payments as provided in clause (C)(2) of
       subsection 4.3(a) or clauses (iii) or (iv) of the first paragraph of
       subsection 4.3(b) and (II) if such proceeds are used to consummate a
       transaction pursuant to which

                                       39


       the Company Incurs Acquired Indebtedness, one-half of the amount of such
       Acquired Indebtedness so Incurred and

            (B) the Fair Market Value of any Permitted Assets acquired by the
       Company in exchange for Equity Interests of the Company issued after the
       Issue Date; provided, however, that in determining the Fair Market Value
       of any such Permitted Assets so acquired, if the estimated Fair Market
       Value of such Permitted Assets exceeds (x) C2.0 million, then the Fair
       Market Value of such Permitted Assets will be determined by a majority of
       the Board of Directors, which determination will be evidenced by a
       resolution thereof, and (y) C10.0 million, then the Company will deliver
       the Trustee a written appraisal as to the fair market value of such
       Permitted Assets prepared by an internationally recognized investment
       banking or public accounting firm (or, if no such investment banking or
       public accounting firm is qualified to prepare such an appraisal, by an
       internationally recognized appraisal firm); and provided further that
       such Indebtedness (other than the Indebtedness Incurred under one or more
       Credit Facilities, under one or more Capitalized Leases or from the
       vendor of assets, property or services acquired with the proceeds of such
       Indebtedness) does not mature prior to the Stated Maturity of the Notes
       and the Weighted Average Life to Maturity of such Indebtedness is longer
       than that of the Notes;

       (xi)  Indebtedness outstanding as of the Issue Date; and

       (xii)  Unsecured Indebtedness of the Company (in addition to Indebtedness
     permitted under clauses (i) through (xi) above) in an aggregate principal
     amount outstanding at any one time not to exceed C200.0 million.

       (c) For purposes of determining any particular amount of Indebtedness
under subsection 4.4, Guarantees, Liens or obligations with respect to letters
of credit supporting Indebtedness otherwise included in the determination of
such particular amount shall not be included; provided, however, that the
foregoing shall not in any way be deemed to limit the provisions of Section
4.17.  For purposes of determining compliance with this Section 4.4, (A) in the
event that an item of Indebtedness meets the criteria of more than one of the
types of Indebtedness described in the above clauses of subsection 4.4(b), the
Company, in its sole discretion, shall classify such item of Indebtedness and
only be required to include the amount and type of such Indebtedness in one of
such clauses and (B) the principal amount of Indebtedness issued at a price that
is less than the principal amount thereof shall be equal to the amount of the
liability in respect thereof determined in conformity with U.S. GAAP.

       (d) For purposes of determining compliance with any Euro-denominated
restriction on the Incurrence of Indebtedness, the Euro-equivalent principal
amount of Indebtedness denominated in a non-Euro currency shall be calculated
based on the relevant currency exchange rate in effect on the date such
Indebtedness was Incurred, in the case of term Indebtedness, or first committed,
in the case of revolving credit Indebtedness; provided that if such Indebtedness
is Incurred to refinance other Indebtedness denominated in a non-Euro currency,
and such refinancing would cause the applicable Euro-denominated restriction to
be exceeded if calculated at the relevant currency exchange rate in effect on
the date of such refinancing, such Euro-

                                       40


denominated restriction shall be deemed not to have been exceeded so long as the
principal amount of such refinancing Indebtedness does not exceed the principal
amount of such Indebtedness being refinanced. The principal amount of any
Indebtedness incurred to refinance other Indebtedness, if Incurred in a
different currency from the Indebtedness being refinanced, shall be calculated
based on the currency exchange rate applicable to the currencies in which such
refinancing Indebtedness is denominated that is in effect on the date of such
refinancing.

       SECTION 4.5  Corporate Existence.  Except as otherwise permitted by
                    -------------------
Article V, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and the
corporate, partnership, limited liability or other existence of each of its
Subsidiaries in accordance with the respective organizational documents (as the
same may be amended from time to time) of each Subsidiary and the rights
(charter and statutory) of the Company and each of its Subsidiaries; provided,
however, that the Company shall not be required to preserve any such right, or
the corporate, partnership, limited liability or other existence of any
Subsidiary, if the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and each of its Subsidiaries, taken as a whole, and that the loss
thereof is not, and will not be, adverse in any material respect to the Holders.

       SECTION 4.6  Payment of Taxes and Other Claims.  The Company shall pay or
                    ---------------------------------
discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all material taxes, assessments and governmental charges levied
or imposed upon it or any of its Subsidiaries or upon the income, profits or
property of it or any of its Subsidiaries and (ii) all lawful claims for labor,
materials and supplies which, in each case, if unpaid, might by law become a
material liability or Lien upon the property of it or any of its Subsidiaries;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings and for which appropriate provision has been made.

       SECTION 4.7  Maintenance of Properties and Insurance.  (a)  The Company
                    ---------------------------------------
shall cause all material properties owned by or leased by it or any of its
Subsidiaries useful and necessary to the conduct of its business or the business
of any of its Subsidiaries to be improved or maintained and kept in normal
condition, repair and working order and shall cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
its judgment may be necessary, so that the business carried on in connection
therewith may be properly conducted at all times; provided, however, that
nothing in this Section 4.7 shall prevent the Company or any of its Subsidiaries
from discontinuing the use, operation or maintenance of any of such properties,
or disposing of any of them, if such discontinuance or disposal is, in the
judgment of the Board of Directors or of the board of directors of any
Subsidiary of the Company concerned, or of an officer (or other agent employed
by the Company or of any of its Subsidiaries) of the Company or any of its
Subsidiaries having managerial responsibility for any such property, desirable
in the conduct of the business of the Company or any Subsidiary of the Company,
and if such discontinuance or disposal is not adverse in any material respect to
the Holders.

                                       41


       (b) To the extent available at commercially reasonable rates, the Company
shall maintain, and shall cause its Subsidiaries to maintain, insurance with
responsible carriers against such risks and in such amounts, and with such
deductibles, retentions, self-insured amounts and co-insurance provisions, as
are customarily carried by similar businesses of similar size.

       SECTION 4.8  Compliance Certificate; Notice of Default.  (a)  The Company
                    -----------------------------------------
shall deliver to the Trustee, within 90 days after the close of each fiscal

Company and its Subsidiaries during the preceding fiscal year has been made
under the supervision of the signing Officers with a view to determining whether
it has kept, observed, performed and fulfilled, and has caused each of its
Subsidiaries to keep, observe, perform and fulfill its obligations under this
Indenture and the Collateral Agreement and further stating, as to each such
Officer signing such certificate, that, to the best of his or her knowledge, the
Company during such preceding fiscal year has kept, observed, performed and
fulfilled, and has caused each of its Subsidiaries to keep, observe, perform and
fulfill each and every such covenant contained in this Indenture and the
Collateral Agreement and no Default occurred during such year and at the date of
such certificate there is no Default which has occurred and is continuing or, if
such signers do know of such Default, the certificate shall describe its status,
with particularity and that, to the best of his or her knowledge, no event has
occurred and remains by reason of which payments on the account of the principal

any, on the Notes is prohibited or if such event has occurred, a description of
the event and what action each is taking or proposes to take with respect
thereto.  The Officers' Certificate shall also notify the Trustee should the
Company elect to change the manner in which it fixes its fiscal year end.  The
Company shall notify the Trustee of any default or defaults in the performance
of any covenants or agreements under this Indenture or the Collateral Agreement
within five Business Days of becoming aware of any such default.

       (b) The annual financial statements delivered pursuant to Section 4.10
shall include, so long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, a written report of the
Company's independent accountants (who shall be a firm of established
international reputation) that in conducting their audit of such financial
statements nothing has come to their attention that would lead them to believe
that the Company has violated any provisions of Articles IV, V or VI of this
Indenture or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable directly or indirectly to any Person for any failure to obtain
knowledge of any such violation.

       (c) The Company shall deliver to the Trustee, within 5 Business Days,
upon any officer becoming aware of any Default or any default or event of
default under any document, instrument or agreement representing Indebtedness of
the Company, an Officers' Certificate specifying the Default or such default or

       SECTION 4.9  Compliance with Laws.  The Company shall comply, and shall
                    --------------------
cause each of its Subsidiaries to comply, with all applicable statutes, rules,

all political subdivisions thereof, and of any relevant governmental regulatory
authority, in respect of the conduct of their respective businesses and the
ownership of their respective properties, except for such noncompliances as
would not in the aggregate have a material adverse effect on the financial
condition or results of operations of the Company and its Subsidiaries taken as
a whole.

       SECTION 4.10 Reports.  (a)  The Company will file on a timely basis with
                    -------

Company shall also (a) file with the Trustee, and provide to each holder,
without cost to such holder, copies of such reports and documents within 15 days
after the date on which the Company files such reports and documents with the

                    ---------------------------------------
covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other law that
would prohibit or forgive the Company from paying all or any portion of the
principal of and/or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the

exchange of property or assets, or the rendering of any service) with any direct
or indirect holder (or any Affiliate of such holder) of 5% or more of any class
of Capital Stock of the Company or with any Affiliate of the Company or any
Restricted Subsidiary, unless:

       (i)  such transaction or series of transactions is on terms that are no
     less favorable to the Company or such Restricted Subsidiary than could
     reasonably be obtained in a comparable arm's-length transaction with a
     Person that is not such a holder or Affiliate;

       (ii) if such transaction or series of transactions involves aggregate
     consideration in excess of C2.5 million, the Company shall have delivered
     to the Trustee a resolution set forth in an Officers' Certificate adopted
     by a majority of the Board of Directors, including a majority of the
     independent, disinterested directors, approving such transaction or series
     of transactions and certifying that such transaction or series of
     transactions comply with paragraph (i) above; and

       (iii) if such transaction or series of transactions involves aggregate
     consideration in excess of C7.5 million, the Company shall have delivered
     to the Trustee a written opinion as to the fairness to the Company or such
     Restricted Subsidiary of such transaction or series of transactions from a
     financial point of view from an internationally recognized investment
     banking firm (or, if an investment banking firm is generally not qualified
     to give such an opinion, by an internationally recognized appraisal firm or
     accounting firm).

       (b) The foregoing limitation does not limit and will not apply to (i) any
transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries; (ii) the payment of reasonable and customary
regular fees to directors of the Company who are not employees of the Company;

any other Person with which the Company files a

                                       44


consolidated tax return or with which the Company is part of a consolidated
group for tax purposes.

       SECTION 4.13 Limitation on Dividend and Other Payment Restrictions
                    -----------------------------------------------------
Affecting Restricted Subsidiaries.  (a)  The Company will not, and will not
- ---------------------------------
permit any Restricted Subsidiary to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any consensual encumbrance or
restriction of any kind on the ability of any Restricted Subsidiary to:

                (i) pay dividends or make any other distributions permitted by
       applicable law on any Equity Interests of such Restricted Subsidiary
       owned by the Company or any other Restricted Subsidiary,

       Restricted Subsidiary, or

                (iv) transfer any of its property or assets to the Company or
       any other Restricted Subsidiary.

       (b) The foregoing provisions shall not prohibit any encumbrances or
restrictions: (i) existing under or by reason of any agreement in effect on the
Issue Date, and any amendments, supplements, extensions, refinancings, renewals
or replacements of such agreements; provided that the encumbrances and
restrictions in any such amendments, supplements, extensions, refinancings,
renewals or replacements are no more restrictive than those encumbrances or
restrictions that are then in effect and that are being amended, supplemented,
extended, refinanced, renewed or replaced; (ii) existing under or by reason of
applicable law; (iii) existing with respect to any Restricted Subsidiary
acquired by the Company or any Restricted Subsidiary after the Issue Date, or
the property or assets of such Restricted Subsidiary, and existing at the time
of such acquisition and not incurred in contemplation thereof, which
encumbrances or restrictions are not applicable to any Person or the property or
assets of any Person other than such Person or the property or assets of such
Person so acquired; (iv in the case of clause (iv) of subsection 4.13(a), (A)
that restrict in a customary manner the subletting, assignment or transfer of
any property or asset that is, or is subject to, a lease, purchase mortgage
obligation, license, conveyance or contract or similar property or asset, (B)
existing by virtue of any transfer of, agreement to transfer, option or right
with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by this Indenture or (C) arising
or agreed to in the ordinary course of business, not relating to any
Indebtedness, and that do not, individually or in the aggregate, materially
detract from the value of property or assets of the Company or any Restricted
Subsidiary to the Company or any Restricted Subsidiary; (v) with respect to a
Restricted Subsidiary and imposed pursuant to an agreement that has been entered
into for the sale or disposition of all or substantially all of the Capital
Stock in, or property and assets of, such Restricted Subsidiary; provided that
such restriction shall terminate if such transaction is abandoned or if such
transaction is not consummated within six months of the date

                                       45


such agreement was entered into; or (vi) contained in the terms of any
Indebtedness or any agreement pursuant to which such Indebtedness was issued if
(A) the encumbrance or restriction applies only in the event of a payment
default or a default with respect to a financial covenant contained in such
Indebtedness or agreement, (B) the encumbrance or restriction is not materially
more disadvantageous to the holders of the Notes than is customary in comparable
financings (as determined by the Board of Directors) and (C) the Board of
Directors determines that any such encumbrance or restriction will not
materially affect the Company's ability to make principal or interest payments
on the Notes.

       (c) Nothing contained in this Section 4.13 shall prevent the Company or
any Restricted Subsidiary from creating, incurring, assuming or suffering to
exist any Liens otherwise permitted in Section 4.14 that limit the right of the
debtor to dispose of the assets securing such Indebtedness.

       SECTION 4.14 Limitation on Liens.  The Company will not, and will not
                    -------------------

assume or suffer to exist any Lien (other than Permitted Liens) on any asset or
property of the Company or any Restricted Subsidiary without making effective
provisions for all of the Notes and all other amounts due under this Indenture
to be directly secured equally and ratably with (or, if the obligation or
liability to be secured by such Lien is subordinated in right of payment to the
Notes, prior to) the obligation or liability secured by such Lien; provided that
any Lien which is granted to secure the Notes under this covenant shall be
discharged at the same time as the discharge of the Lien that gave rise to the
obligation to so secure the Notes.

       SECTION 4.15 Change of Control.  (a)  Upon the occurrence of a Change of
                    -----------------
Control, the Company will make an offer to purchase all or any part (equal to
$1,000 in principal amount and integral multiples thereof) of the Notes pursuant
to the offer described below (the "Change of Control Offer") at a price in cash
                                   -----------------------
(the "Change of Control Payment") equal to 101% of the aggregate principal
      -------------------------
amount thereof plus accrued and unpaid interest, thereon to the date of
repurchase, plus Additional Amounts, if any, and Liquidated Damages, if any, to
the date of repurchase (and in the case of Definitive Notes, subject to the
right of Holders of record on the relevant record date to receive interest and
Liquidated Damages, if any, due on the relevant interest payment date and
Additional Amounts, if any, in respect thereof).  Within 30 days following any
Change of Control, the Company will publish notice of such in a leading
newspaper having a general circulation in New York (which is expected to be The
Wall Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allgemeine Zeitung) (and, if and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
a newspaper having a general circulation in Luxembourg (which is expected to be
the Luxemburger Wort)) or, in the case of Definitive Notes, mail a notice to
each Holder (and if and so long as the Notes are listed on the Luxembourg Stock
Exchange and the rules of such stock exchange shall so require, will publish
notice in a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)), with a copy to the Trustee, with the
following information: (i) a Change of Control Offer is being made pursuant to
this Section 4.15 and all Notes properly tendered pursuant to such Change of
Control Offer will be accepted for payment; (ii) the purchase price and the
purchase date, which will be no earlier than 30 days nor later than 60 days from
the date such notice is published, or where

                                       46


relevant, mailed, except as may be otherwise required by applicable law (the
"Change of Control Payment Date"); (iii) any Note not properly tendered will
 ------------------------------
remain outstanding and continue to accrue interest and Liquidated Damages, if
any; (iv) unless the Company defaults in the payment of the Change of Control
Payment, all Notes accepted for payment pursuant to the Change of Control Offer
will cease to accrue interest and Liquidated Damages, if any, on the Change of
Control Payment Date; (v) Holders electing to have any Notes purchased pursuant
to a Change of Control Offer will be required to surrender the Notes, with the
form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes
completed, to the Paying Agent or a depositary and at the address specified in
the notice prior to the close of business on the third Business Day preceding
the Change of Control Payment Date; (vi) Holders will be entitled to withdraw
their tendered Notes and their election to require the Company to purchase such
Notes; provided that the Paying Agent or a depositary receives, not later than
the close of business on the last Business Day of the offer period, a facsimile
transmission or letter setting forth the name of the Holder, the principal

new Notes equal in principal amount to the unpurchased portion of the principal
amount of the Notes surrendered, which unpurchased portion must be equal to
$1,000 in principal amount or an integral multiple thereof.

       The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder and will
comply with the applicable laws of any non-U.S. jurisdiction in which a Change
of Control Offer is made, in each case, to the extent such laws or regulations

Change of Control Offer.  To the extent that the provisions of any securities
laws or regulations conflict with the provisions of this Indenture, the Company
will comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations contained in this Indenture by virtue
thereof. The provisions relating to the Company's obligation to make an offer to

of partial payment, endorsement) of the Global Notes or (y) in the case of
Definitive Notes, mail to each Holder of Notes, the Change of Control Payment
for such Notes, and the Trustee will promptly authenticate and deliver to the
Holder of the Global Notes a new Global Note or Notes or, in the case of
Definitive Notes, mail to each Holder a new Definitive Note, as applicable,
equal in principal amount to any unpurchased portion of the Notes surrendered,
if any; provided, however, that each new Definitive Note and Global Note will be
in a principal amount of $1,000 or an integral multiple

                                       47

       SECTION 4.16 Limitation on Asset Sales.  (a)  The Company will not, and
                    -------------------------
will not permit any Restricted Subsidiary to, make any Asset Sale unless (i) the
Company or the Restricted Subsidiary, as the case may be, receives consideration
at the time of such Asset Sale at least equal to the Fair Market Value of the
assets sold or disposed of and (ii) at least 75% of the consideration received
for such Asset Sale consists of cash or Cash Equivalents or Replacement Assets
or the assumption of Indebtedness which ranks equal in right of payment with the
Notes.

       (b)  The Company shall, or shall cause the relevant Restricted Subsidiary
to, apply the Net Cash Proceeds from an Asset Sale within 360 days of the
receipt thereof to (A) permanently prepay, repay or purchase unsubordinated
Indebtedness of the Company or any Restricted Subsidiary providing a Guarantee
pursuant to Section 4.17 or Indebtedness of any other Restricted Subsidiary, in
each case owing to a Person other than the Company or any of its Restricted
Subsidiaries, and elect to permanently reduce the commitments thereunder by the
amount of such Indebtedness prepaid, repaid or purchased, (B) invest in
Replacement Assets or (C) in any combination of prepayment, repayment, purchase
and reinvestment permitted by the foregoing clauses (A) and (B).

       Any Net Cash Proceeds from such Asset Sale that are not invested as
provided and within the time period set forth in the first sentence of this
subsection will be deemed to constitute "Excess Proceeds."  If at any time the
                                         ---------------
aggregate amount of Excess Proceeds exceeds C5.0 million, the Company shall,
within 15 Business Days thereafter, make an offer to all Holders of Notes (an

"Asset Sale Offer") to purchase on a pro rata basis the maximum principal amount
- -----------------
of Notes, that is an integral multiple of $1,000 that may be purchased out of
the Excess Proceeds at an offer price in cash in an amount equal to 100% of the
outstanding principal amount thereof, plus accrued and unpaid interest thereon,
plus Additional Amounts, if any, and Liquidated Damages, if any, to the date
fixed for the closing of such offer (and, in the case of Definitive Notes,
subject to the right of a Holder of record on the relevant record date to
receive interest and Liquidated Damages, if any, due on the relevant interest
payment date and Additional Amounts, if any, in respect thereof), in accordance
with the procedures set forth in this Indenture. The Company will commence an
Asset Sale Offer by publishing and mailing the notice required pursuant to the
terms of this Indenture, with a copy to the Trustee. To the extent that the
aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, subject to applicable law, the Company may use any
remaining Excess Proceeds for general corporate purposes.  If the aggregate
principal amount of Notes surrendered by Holders thereof exceeds the amount of
Excess Proceeds, the selection of such Notes for purchase will be made by the
Trustee in the same manner as the Notes are redeemed, as provided in Section
3.1.  Upon completion of any such Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero.

       The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period").  No later than five
                                           ------------
Business Days after the termination of the Offer Period (the "Purchase Date"),
                                                              -------------
the Company shall purchase the maximum principal amount of

                                       48


Notes that may be purchased with such Excess Proceeds (or such pro rata portion)
(which maximum principal amount of Notes shall be the "Offer Amount") or, if
                                                       ------------
less than the Offer Amount has been tendered, all Notes tendered in response to
the Asset Sale Offer.

       If the Purchase Date is on or after an interest Record Date and on or
before the related Interest Payment Date, any accrued and unpaid interest will
be paid in the case of a Global Note, to the Holder thereof or, in the case of a
Definitive Note, to the Person in whose name such Definitive Note is registered
at the close of business on such Record Date, and no additional interest will be
payable to Holders with respect to Notes tendered pursuant to the Asset Sale
Offer.

       At least 30 days but not more than 60 days before a Purchase Date, the
Company shall publish in a leading newspaper having a general circulation in New
York (which is expected to be The Wall Street Journal) and in Frankfurt (which
is expected to be the Frankfurter Allgemeine Zeitung) (and, if and so long as
the Notes are listed on the Luxembourg Stock Exchange and the rules of such
Stock Exchange shall so require, a newspaper having a general circulation in
Luxembourg (which is expected to be the Luxemburger Wort)) or, in the case of
Definitive Notes, mail to Holders by first-class mail, postage prepaid, at their
respective addresses as they appear on the registration books of the Registrar
with a copy of such notice to the Trustee (and, if and so long as the Notes are
listed on the Luxembourg Stock Exchange and the rules of such Stock Exchange
shall so require, publish in a newspaper having a general circulation in
Luxembourg (which is expected to be the Luxemburger Wort)).  The notice shall
contain all instructions and materials (or instructions on how to obtain
instructions and materials) necessary to enable such Holders to tender Notes
pursuant to the Asset Sale Offer.  The Asset Sale Offer shall be made to all
Holders.  The notice, which shall govern the terms of the Asset Sale Offer,
shall state:

               (A)  that the Asset Sale Offer is being made pursuant to this
          Section 4.16 and the length of time the Asset Sale Offer shall remain
          open;

               (B)  the Offer Amount (including the amount of accrued and unpaid
          interest, if any), the purchase price and the Purchase Date;

               (C)  that any Note or portion thereof not tendered or accepted
          for payment shall continue to accrue interest, Additional Amounts, if
          any, and Liquidated Damages, if any, in accordance with the terms
          thereof;

               (D)  that, unless the Company defaults in making payment therefor
          any Note or portion thereof accepted for payment pursuant to the Asset
          Sale Offer shall cease to accrue interest, Additional Amounts, if any,
          and Liquidated Damages, if any, after the Purchase Date;

               (E)  (1) if any Global Note is being purchased in part, the
          portion of the principal amount of such Note to be purchased and that,
          after the Purchase Date, interest, Additional Amounts, if any, and
          Liquidated Damages, if any, shall cease to accrue on the portion to be
          purchased, and upon surrender of such Global Note, the Global Note

                                       49


          with a notation on Schedule A thereof adjusting the principal amount
          thereof to be equal to the unpurchased portion, will be returned and
          (2) if a Definitive Note may be purchased in part, that, after the
          Purchase Date, upon surrender of such Definitive Note, a new
          Definitive Note or Notes in aggregate principal amount equal to the
          unpurchased portion thereof will be issued in the name of the Holder
          thereof, upon cancellation of the original Note;

               (F)  that Holders electing to have a Note or portion thereof
          purchased pursuant to any Asset Sale Offer shall be required to
          surrender the Note, with the form entitled "Option of Holder to Elect
          Purchase" on the reverse of the Note completed, to the Company, a
          depositary, if appointed by the Company, or a Paying Agent at the
          address specified in the notice at least three Business Days before
          the Purchase Date and must complete any form letter of transmittal
          proposed by the Company and acceptable to the Trustee and the Paying
          Agent;

               (G)  that, subject to applicable law, Holders shall be entitled
          to withdraw their election if the Company, depositary or Paying Agent,
          as the case may be, receives, not later than the second Business Day
          before the Purchase Date, a facsimile transmission or letter setting
          forth the name of the Holder, the principal amount of the Note or
          portion thereof the Holder delivered for purchase, the Note
          certificate number and a statement that such Holder is withdrawing his
          election to have the Note or portion thereof purchased;

               (H)  that, if the aggregate principal amount of Notes tendered by
          Holders exceeds the Offer Amount, the selection of such Notes for
          purchase will be made by the Trustee in compliance with the
          requirements of the principal securities exchange, if any, on which
          such Notes are listed, or if such Notes are not so listed or such
          exchange prescribes no method of selection, subject to applicable law,
          on a pro rata basis by lot or by such other method as the Trustee in
          its sole discretion shall deem fair and appropriate (and in such
          manner as complies with applicable legal and exchange requirements);
          provided, however, that no Notes of $1,000 or less shall be purchased
          in part; provided further, that, subject to applicable law, in the
          event of partial purchase by lot, the particular Notes to be purchased
          shall be selected, unless otherwise provided herein, by the Registrar
          or Trustee from the outstanding Notes not previously called for
          purchase; and

               (I)  the instructions that Holders must follow to tender their
          Notes.

       On or before the Purchase Date, the Company shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes or portions
thereof tendered, and deliver to the Trustee an Officers' Certificate stating
that such Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 4.16.  On the Purchase Date, the
Paying Agent shall promptly cause the principal amount of any Global Note so
tendered to be adjusted on Schedule A thereof to be equal to any unpurchased
portion of such Global Note which

                                       50


unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof, and shall promptly authenticate and mail or deliver to each
tendering Holder of a Definitive Note, a new Definitive Note or Notes equal in
principal amount to any unpurchased portion of the Definitive Note surrendered
which unpurchased portion must be equal to $1,000 in principal amount or an
integral multiple thereof. DTC, the Paying Agent or the Company, as the case may
be, shall promptly (but in any case not later than five Business Days after the
Purchase Date) mail or deliver to each tendering Holder an amount equal to the
Offer Amount of the Notes tendered by such Holder and accepted by the Company
for purchase. Any Notes not so accepted shall be promptly mailed or delivered by

breached its obligations described in this Indenture by virtue thereof.

Subsidiary, directly or indirectly, to guarantee, assume or in any other manner
become liable with respect to any Indebtedness of the Company unless (i) such
Restricted Subsidiary simultaneously executes and delivers a supplemental
indenture to this Indenture providing for a Guarantee of all of the Company's
obligations under the Notes and this Indenture on terms substantially similar to
the guarantee of such Indebtedness, except that if such Indebtedness is by its
express terms subordinated in right of payment to the Notes, any such
assumption, Guarantee or other liability of such Restricted Subsidiary with
respect to such Indebtedness shall be subordinated in right of payment to such
Restricted Subsidiary's assumption, Guarantee or other liability with respect to
the Notes substantially to the same extent as such Indebtedness is subordinated
to the Notes and (ii) such Restricted Subsidiary waives, and will not in any
manner whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary as a result of any payment by such Restricted
Subsidiary under its Guarantee; provided that any Restricted Subsidiary may
guarantee Indebtedness of the Company under a Credit Facility if such
Indebtedness is Incurred in accordance with Section 4.4; and provided further
that this paragraph shall not be applicable to any Guarantee of any Restricted
Subsidiary that existed at the time such Person became a Restricted Subsidiary
and was not incurred in connection with, or in contemplation of, such Person
becoming a Restricted Subsidiary.

       (b) Notwithstanding the foregoing subsection (a), any Guarantee of all of
the Company's obligations under the Notes and this Indenture by a Restricted
Subsidiary may provide by its terms that it will be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of

     or more in aggregate principal amount of the Notes;

       (f)  a default occurs on any other Indebtedness of the Company or any
     Restricted Subsidiary if (i) either (x) such default is a failure to pay
     principal of such Indebtedness when due after any applicable grace period
     or (y) as a result of such default, the maturity of such Indebtedness has
     been accelerated prior to its scheduled maturity and such default has not
     been cured within the shorter of 30 days and the applicable grace period,

     so covered), which final judgments remain unpaid, undischarged and unstayed
     for a period in excess of 30 consecutive days following entry of the final
     judgment or order that causes the aggregate amount for all such final
     judgments or orders outstanding and not paid, discharged or stayed to
     exceed C5.0 million;

       (i)  the Company or any of its Significant Subsidiaries (A) commences a

       (j)  the Company challenges the Lien on the Collateral under the
     Collateral Agreement prior to such time as the Collateral is to be released
     to the Company, or the Collateral shall become subject to any Lien other

       SECTION 6.2  Acceleration.  If an Event of Default (other than an Event
                    ------------
of Default specified in Sections 6.1(h) or (i)) occurs and is continuing, the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding, by written notice to the Company, may declare the
principal of, premium, if any, interest and other monetary obligations
(including Additional Amounts, if any, and Liquidated Damages, if any) on all
the then outstanding Notes to be immediately due and payable. Upon such a
declaration, such principal of, premium, if any, interest and other monetary
obligations on the Notes shall be immediately due and payable.  In the event of
a declaration of acceleration because an Event of Default set forth in
subsection 6.1(f) above has occurred and is continuing, such declaration of
acceleration shall be automatically rescinded and annulled if the event of
default triggering such Event of Default pursuant to subsection 6.1(f) shall be
remedied or cured by the Company and/or the relevant Restricted Subsidiaries or
waived by the holders of the relevant Indebtedness within 60 days after the
declaration of acceleration with respect thereto.  If an Event of Default
specified in subsections 6.1(h) or (i) above occurs, the principal of, premium,
if any, accrued interest and other monetary obligations on the Notes then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

       The Trustee shall have no obligation to accelerate the Notes if in the
best judgment of the Trustee acceleration is not in the best interest of the
Holders of such Notes.

       SECTION 6.3  Other Remedies.  If an Event of Default occurs and is
                    --------------
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the

                                       56


payment of principal of or, premium, if any, interest, Additional Amounts, if
any, or Liquidated Damages, if any, on the Notes or to enforce the performance
of any provision of the Notes or this Indenture.

       SECTION 6.4  The Trustee May Enforce Claims Without Possession of
                    ----------------------------------------------------
Securities. All rights of action and claims under this Indenture or the Notes
- ----------
may be prosecuted and enforced by the Trustee without the possession of any of
the Notes or the production thereof in any proceeding relating thereto.

       SECTION 6.5  Rights and Remedies Cumulative.  Except as otherwise
                    ------------------------------
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Notes in Section 2.8, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Notes is intended to be exclusive
of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent or subsequent assertion or employment of any
other appropriate right or remedy.

       SECTION 6.6  Delay or Omission Not Waiver.  No delay or omission of the
                    ----------------------------
Trustee or of any Holder of any Note to exercise any right or remedy accruing
upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.  Every right and
remedy given by this Article or by law to the Trustee or to the Holders of Notes
may be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by the Holders of Notes.

       SECTION 6.7  Waiver of Past Defaults.  Subject to Sections 6.10 and 9.2,
                    -----------------------
at any time after a declaration of acceleration with respect to the Notes as
described in Section 6.1, the Holders of at least a majority in principal amount
of the outstanding Notes by written notice to the Company and to the Trustee,
may waive all past defaults and rescind and annul a declaration of acceleration
and its consequences if (i) all existing Events of Default, other than the
nonpayment of the principal of, premium, if any, interest and other monetary
obligations on the Notes that have become due solely by such declaration of
acceleration, have been cured or waived and (ii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction.  Such
waiver shall not excuse a continuing Event of Default in the payment of
interest, premium, if any, principal, Additional Amounts, if any, or Liquidated
Damages, if any, on such Note held by a non-consenting Holder, or in respect of
a covenant or a provision which cannot be amended or modified without the
consent of all Holders. In the event of any Event of Default specified in
subsection 6.1(f), such Event of Default and all consequences thereof
(including, without limitation, any acceleration or resulting payment default)
shall be annulled, waived and rescinded, automatically and without any action by
the Trustee or the Holders of the Notes, if within 60 days after such Event of
Default arose (x) the Indebtedness or guarantee that is the basis for such Event
of Default has been discharged, or (y) the holders thereof have rescinded or
waived the acceleration, notice or action (as the case may be) giving rise to
such Event of Default, or (z) if the default that is the basis for such Event of
Default has been cured.  The Company shall deliver to the Trustee an Officers'
Certificate stating

                                       57


that the requisite percentage of Holders have consented to such waiver and
attaching copies of such consents. When a Default or Event of Default is waived,
it is cured and ceases.

       SECTION 6.8  Control by Majority.  Subject to Section 2.10, the Holders
                    -------------------
of not less than a majority in principal amount of the outstanding Notes may, by
written notice to the Trustee, direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on it.  Subject to Section 7.1, however, the Trustee may
refuse to follow any direction that conflicts with any law or this Indenture
that the Trustee determines may be unduly prejudicial to the rights of another
Holder of Notes, or that may involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction.

       SECTION 6.9  Limitation on Suits.  A Holder of Notes may not pursue any
                    -------------------
remedy with respect to this Indenture or the Notes unless:

       (i)  the Holder gives to the Trustee written notice of a continuing Event
     of Default;

       (ii) the Holder or Holders of at least 25% in principal amount of the
     outstanding Notes make a written request to the Trustee to pursue the
     remedy;

       (iii) such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

       (iv) the Trustee does not comply with the request within 30 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

       (v)  during such 30-day period the Holder or Holders of a majority in
     principal amount of the outstanding Notes do not give the Trustee a
     direction which, in the opinion of the Trustee, is inconsistent with the
     request.

       A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over such other Holder.

       SECTION 6.10 Rights of Holders To Receive Payment.  Notwithstanding any
                    ------------------------------------
other provision of this Indenture, the right of any Holder to receive payment of
principal of, premium, if any, interest, Additional Amounts, if any and
Liquidated Damages, if any, on a Note, on or after the respective due dates
expressed in such Note, or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

       SECTION 6.11 Collection Suit by Trustee.  If an Event of Default in
                    --------------------------
payment of principal, premium, if any, interest, Additional Amounts, if any or
Liquidated Damages, if any, specified in subsection 6.1(a) or (b) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company or any other obligor on the Notes for the
whole amount of principal and accrued interest remaining unpaid, together with

                                       58


interest on overdue principal and, to the extent that payment of such interest
is lawful, interest on overdue installments of interest, in each case at the
rate per annum borne by the Notes and such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.7.

       SECTION 6.12 Trustee May File Proofs of Claim.  The Trustee may file such
                    --------------------------------
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, accountants and experts) and the Holders allowed in any
judicial proceedings relating to the Company, its creditors or its property or
other obligor on the Notes, its creditors and its property and shall be entitled
and empowered to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same, and any Custodian in
any such judicial proceedings is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agent and counsel, and any other amounts due the
Trustee under Section 7.7. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.7 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties which the
Holders of the Notes may be entitled to receive in such proceeding whether in
liquidation or under any plan of reorganization or arrangement or otherwise.

       SECTION 6.13 Priorities.  If the Trustee collects any money or property
                    ----------
pursuant to this Article VI, it shall pay out the money or property in the
following order:

       First:  to the Trustee, the Agents and their agents and attorneys for
       amounts due under Section 7.7, including payment of all compensation,
       expense and liabilities incurred, and all advances made, by the
       Trustee and the costs and expenses of collection;

       Second:  to Holders for amounts due and unpaid on the Notes for
       principal, premium, if any, interest, Additional Amounts, if any and
       Liquidated Damages, if any, ratably, without preference or priority of
       any kind, according to the amounts due and payable on the Notes for
       principal, premium, if any, interest, Additional Amounts, if any, and
       Liquidated Damages, if any, respectively; and

       Third:  to the Company or any other obligor on the Notes, as their
       interests may appear, or as a court of competent jurisdiction may
       direct.

       The Trustee, upon prior notice to the Company, may fix a record date and
payment date for any payment to Holders pursuant to this Section 6.13; provided
that the failure to give any such notice shall not affect the establishment of
such record date or payment date for Holders pursuant to this Section 6.13.

                                       59


       SECTION 6.14 Restoration of Rights and Remedies.  If the Trustee or any
                    ----------------------------------
Holder of any Note has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case, subject to any determination in such proceeding,
the Company, the Trustee and the Holders of Notes shall be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders of Notes shall continue as though no
such proceeding had been instituted.

       SECTION 6.15 Undertaking for Costs.  In any suit for the enforcement of
                    ---------------------
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant.  This Section 6.15 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.10, or a suit
by a Holder or Holders of more than 10% in principal amount of the outstanding
Notes.

       SECTION 6.16 Compliance Certificate; Notices of Default.  The Company is
                    ------------------------------------------
required to deliver to the Trustee annually a statement, in the form of an

is required, within five Business Days, upon becoming aware of any Default or
Event of Default or any default under any document, instrument or agreement

                                    -------

       SECTION 7.1  Duties of Trustee.  (a)  If an Event of Default actually
                    -----------------
known to a Trust Officer of the Trustee has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.  Subject to such provisions, the Trustee will be under
no obligation to exercise any of its rights or powers under this Indenture at
the request of any of the Holders of Notes, unless they shall have offered to
the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

       (b) Except during the continuance of an Event of Default actually known
to the Trustee:

           (i) The Trustee and the Agents will perform only those duties as are
       specifically set forth herein and no others and no implied covenants or
       obligations shall be read into this Indenture against the Trustee or the
       Agents.

                                       60


           (ii) In the absence of bad faith on their part, the Trustee and the
       Agents may conclusively rely, as to the truth of the statements and the
       correctness of the opinions expressed therein, upon certificates or
       opinions and such other documents delivered to the Trustee and conforming
       to the requirements of this Indenture. However, in the case of any such
       certificates or opinions which by any provision hereof are required to be
       furnished to the Trustee, the Trustee shall examine the certificates and
       opinions to determine whether or not they conform to the requirements of
       this Indenture but need not confirm or investigate the accuracy of
       mathematical calculations or other facts stated therein.

       (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except
that:

           (i) This paragraph does not limit the effect of subsection (b) of
       this Section 7.1.

           (ii) Neither the Trustee nor Agent shall be liable for any error
       of judgment made in good faith by a Trust Officer of such Trustee or
       Agent, unless it is proved that the Trustee or such Agent was
       negligent in ascertaining the pertinent facts.

           (iii) The Trustee shall not be liable with respect to any action
       it takes or omits to take in good faith in accordance with a direction
       received by it pursuant to Section 6.8.

       (d) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder or to take or omit to take any action under this
Indenture or take any action at the request or direction of Holders if it shall
have reasonable grounds for believing that repayment of such funds is not
assured to it or it does not receive an indemnity satisfactory to it in its sole
discretion against such risk, liability, loss, fee or expense which might be
incurred by it in compliance with such request or direction.

       (e) Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to subsections (a),
(b), (c) and (d) of this Section 7.1.

       (f) The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company.  Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

       (g) Any provision hereof relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 7.1 and, upon qualification of this Indenture under
the TIA, the TIA.

     Agent them to be genuine and to have been signed or presented by the proper

     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     consent order, approval, appraisal, bond, debenture, note, coupon, security
     or other paper or document, but the Trustee or the Agent, as the case may
     be, in its discretion, may make reasonable further inquiry or investigation
     into such facts or matters stated in such document and if the Trustee or
     the Agent as the case may be, shall determine to make such further inquiry
     or investigation, it shall be entitled to examine the books, records and
     premises of the Company, at reasonable times during normal business hours,
     personally or by agent or attorney and the Trustee and the Agent shall
     incur no liability or additional liability of any kind by reason of such
     inquiry or investigation. The Trustee shall not be deemed to have notice or
     any knowledge of any matter (including without limitation Defaults or
     Events of Default) unless a Trust Officer assigned to and working in the
     Trustee's Corporate Trust Administration has actual knowledge thereof or
     unless written notice thereof is received by the Trustee, attention:
     Corporate Trust Administration and such notice references the Notes
     generally, the Company or this Indenture;

       (b) Any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate or
     Company Order and any resolution of the Board of Directors of the Company,
     as the case may be, may be sufficiently evidenced by a Board Resolution;

       (c) Before the Trustee and any Agent acts or refrains from acting, it may
     require an Officers' Certificate or an Opinion of Counsel or both, which
     shall conform to the provisions of Sections 11.4 and 11.5.  Neither the
     Trustee nor any Agent shall be liable for any action it takes or omits to
     take in good faith in reliance on such certificate or opinion.

       (d) The Trustee and any Agent may act through their attorneys and agents
     and shall not be responsible for the misconduct or negligence of any agent
     or attorney appointed with due care.

       (e) The Trustee shall not be liable for any action it takes or omits to
     take in good faith which it reasonably believes to be authorized or within
     its rights or powers conferred upon it by this Indenture; provided,
     however, that the Trustee's conduct does not constitute willful misconduct,
     negligence or bad faith.

       (f) The Trustee or any Agent may consult with counsel of its selection
     and the advice or opinion of such counsel shall be full and complete
     authorization and protection from liability in respect of any action taken,
     omitted or suffered by it hereunder in good faith and in accordance with
     the advice or opinion of such counsel.

       (g) Subject to Section 9.2 hereof, the Trustee may (but shall not be
     obligated to), without the consent of the Holders, give any consent, waiver
     or approval required by the terms hereof, but shall not without the consent
     of the Holders of not less than a majority

                                       62

     any consent, waiver or approval or (ii) agree to any amendment or
     modification of this Indenture, in each case, that shall have a material
     adverse effect on the interests of any Holder. The Trustee shall be
     entitled to request and conclusively rely on an Opinion of Counsel with
     respect to whether any consent, waiver, approval, amendment or modification
     shall have a material adverse effect on the interests of any Holder.

       (h) the rights, privileges, protections, immunities and benefits given to
     the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, the Trustee in each of its
     capacities hereunder, and to each agent, custodian and other Person
     employed to act hereunder or in connection with the transactions
     contemplated hereby.

       SECTION 7.3  Individual Rights of Trustee.  The Trustee in its individual
                    ----------------------------
or any other capacity may become the owner or pledgee of Notes and may otherwise
deal with the Company, its Subsidiaries, or their respective Affiliates with the
same rights it would have if it were not Trustee.  Any Agent may do the same
with like rights.  The Trustee must comply with Sections 7.10 and 7.11.

       SECTION 7.4  Trustee's Disclaimer.  The Trustee and the Agents shall not
                    --------------------
be responsible for and make no representation as to the validity, effectiveness
or adequacy of this Indenture or the Notes; the Trustee and the Agents shall not
be accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company or upon the Company's direction under
any provision hereof; the Trustee shall not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee;
and the Trustee and the Agents shall not be responsible for any statement or
recital herein of the Company, or any document issued in connection with the
sale of Notes or any statement in the Notes other than the Trustee's certificate
of authentication.

       SECTION 7.5  Notice of Default.  If an Event of Default occurs and is
                    -----------------
continuing and a Trust Officer of the Trustee receives actual notice of such
event, the Trustee shall mail to each Holder, as their names and addresses
appear on the list of Holders described in Section 2.5, notice of the uncured
Default or Event of Default within 90 days after the Trustee receives such
notice.  Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, interest, Additional Amounts, if any, or
Liquidated Damages, if any, on any Note, including the failure to make payment
on (i) the Change of Control Payment Date pursuant to a Change of Control Offer
or (ii) the Asset Sale Purchase Date pursuant to an Asset Sale Offer, the
Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the interest
of the Holders.

       SECTION 7.6  Report by Trustee to Holders.  This Section 7.6 shall not be
                    ----------------------------
operative as a part of this Indenture until this Indenture is qualified under
the TIA, and, until such qualification, this Indenture shall be construed as if
this Section 7.6 were not contained herein.

      Within 60 days after each June 15 beginning with June 15, 2000, the
Trustee shall, to the extent that any of the events described in TIA Section
313(a) occurred within the previous

                                       63


twelve months, but not otherwise, mail to each Holder a brief report dated as of
such date that complies with TIA Section 313(a). The Trustee also shall comply
with TIA Sections 313(b), 313(c) and 313(d).

       A copy of each report at the time of its mailing to Holders shall be
mailed to the Company and filed with the Commission and each securities
exchange, if any, on which the Notes are listed.

       The Company shall promptly notify the Trustee if subsequent to the date
hereof the Notes become listed on any securities exchange or of any delisting
thereof.

       SECTION 7.7  Compensation and Indemnity.  The Company shall pay to the
                    --------------------------
Trustee from time to time such compensation as the Company and the Trustee shall
from time to time agree in writing for its acceptance of this Indenture and
services hereunder.  The Trustee's and the Agents' compensation shall not be
limited by any law on compensation of a trustee of an express trust.  The
Company shall reimburse the Trustee and the Agents upon request for all
reasonable disbursements, expenses and advances (including reasonable fees and
expenses of counsel) incurred or made by it in addition to the compensation for
their services, except any such disbursements, expenses and advances as may be
attributable to the Trustee's or any Agent's negligence or bad faith.  Such
expenses shall include the reasonable compensation, disbursements and expenses
of the Trustee's and Agents' accountants, experts and counsel and any taxes or
other expenses incurred by a trust created pursuant to Section 8.4 hereof.

       The Company shall indemnify each of the Trustee, any predecessor Trustee
and the Agents for, and hold them harmless against, any and all loss, damage,
claim, expense or liability including taxes (other than taxes based on the
income of the Trustee) incurred by the Trustee or an Agent without negligence,
willful misconduct or bad faith on its part in connection with the acceptance or
administration of this trust and its duties under this Indenture and the
Collateral Agreement and the Unit Agreement, including the reasonable expenses
and attorneys' fees and expenses of defending itself against any claim or
liability arising hereunder.  The Trustee and the Agents shall notify the
Company promptly of any claim asserted against the Trustee or such Agent for
which it may seek indemnity.  However, the failure by the Trustee or the Agent
to so notify the Company shall not relieve the Company of its obligations
hereunder.  The Company shall defend the claim and the Trustee or such Agent
shall cooperate in the defense (and may employ its own counsel reasonably
satisfactory to the Trustee) at the Company's expense.  The Trustee or such
Agent may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel.  The Company need not pay for any settlement made
without its written consent, which consent shall not be unreasonably withheld.
The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee or such Agent as a result of the violation of
this Indenture by the Trustee or such Agent if such violation arose from the
Trustee's or such Agent's negligence or bad faith.

       To secure the Company's payment obligations in this Section 7.7, the
Trustee and the Agents shall have a senior Lien prior to the Notes against all
money or property held or collected by the Trustee and the Agents, in its
capacity as Trustee or Agent, except money or property held

                                       64


in trust to pay principal or premium, if any, or interest on particular Notes
and except for any assets held in the Collateral Account.

       When the Trustee or an Agent incurs expenses or renders services after
the occurrence of an Event of Default specified in subsection 6.1(h) or (i), the
expenses (including the reasonable fees and expenses of its agents and counsel)
and the compensation for the services shall be preferred over the status of the
Holders in a proceeding under any Bankruptcy Law and are intended to constitute
expenses of administration under any Bankruptcy Law. The Company's obligations
under this Section 7.7 and any claim arising hereunder shall survive the
termination of this Indenture, the resignation or removal of any Trustee or
Agent, the discharge of the Company's obligations pursuant to Article VIII and
any rejection or termination under any Bankruptcy Law.

       The provisions of this Section 7.7 shall survive the termination of this
Indenture.

       SECTION 7.8  Replacement of Trustee.  The Trustee may resign at any time
                    ----------------------
by so notifying the Company in writing.  The Holders of a majority in principal
amount of the outstanding Notes may remove the Trustee by so notifying the
Company and the Trustee in writing and may appoint a successor trustee with the
Company's consent.  A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this section.  The Company may remove
the Trustee if:

       (i)  the Trustee fails to comply with Section 7.10;

       (ii) the Trustee is adjudged a bankrupt or an insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

       (iii) a receiver or other public officer takes charge of the Trustee or
     its property; or

       (iv) the Trustee becomes incapable of acting with respect to its duties
     hereunder.

       If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall notify each Holder of such event
and shall promptly appoint a successor Trustee.  Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the then outstanding Notes may, with the Company's consent, appoint a successor
Trustee to replace the successor Trustee appointed by the Company.

       A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company.  Immediately after that, the
retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.7, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.7, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture.  A successor Trustee shall mail notice of its succession to each
Holder.

                                       65


       If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the then outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

       If the Trustee after written request by any Holder who has been a Holder
for at least six months fails to comply with Section 7.10, such Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

       Notwithstanding the replacement of the Trustee pursuant to this Section
7.8, the Company's obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee and the Company shall pay to any replaced or removed
Trustee all amounts owed under Section 7.7 upon such replacement or removal.

       SECTION 7.9  Successor Trustee by Merger, etc.  If the Trustee
                    --------------------------------
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.  In case any Notes shall
have been authenticated, but not delivered, by the Trustee then in office, any
successor by consolidation, merger or conversion to such authenticating Trustee
may adopt such authentication and deliver the Notes so authenticated with the
same effect as if such successor Trustee had itself authenticated such Notes.

       SECTION 7.10 Corporate Trustee Required; Eligibility.   There shall be at
                    ---------------------------------------
all times a Trustee hereunder which shall be eligible to act as Trustee under
the TIA and shall have a combined capital and surplus of at least $50,000,000
and have its Corporate Trust Office in the Borough of Manhattan, The City of New
York.  If such Person publishes reports of condition at least annually, pursuant
to law or to the requirements of a Federal, State or District of Columbia
supervising or examining authority within the United States of America, then for
the purposes of this Section, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

       SECTION 7.11 Disqualification; Conflicting Interests.  If the Trustee has
                    ---------------------------------------
or shall acquire a conflicting interest within the meaning of the TIA, the
Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the TIA and this
Indenture.

       SECTION 7.12 Preferential Collection of Claims Against Company.  The
                    -------------------------------------------------
Trustee, in its capacity as Trustee hereunder, shall comply with TIA Section
311(a), excluding any creditor relationship listed in TIA Section 311(b).  A
Trustee who has resigned or been removed shall be subject to TIA Section 311(a)
to the extent indicated.

                                       66


                                 ARTICLE VIII

                    SATISFACTION AND DISCHARGE OF INDENTURE
                    ---------------------------------------

       SECTION 8.1  Option to Effect Legal Defeasance or Covenant Defeasance.
                    --------------------------------------------------------
The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, with respect to
the Notes, elect to have either Section 8.2 or 8.3 be applied to all outstanding
Notes upon compliance with the conditions set forth below in this Article VIII.

       SECTION 8.2  Legal Defeasance and Discharge.  Upon the Company's exercise
                    ------------------------------
under Section 8.1 of the option applicable to this Section 8.2, the Company
shall be deemed to have been discharged from its obligations with respect to all
outstanding Notes on the date the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, such Legal Defeasance
               ----------------
means that the Company shall be deemed to have paid and discharged all the
Obligations relating to the outstanding Notes and the Notes shall thereafter be
deemed to be "outstanding" only for the purposes of Section 8.6, Section 8.8 and
the other Sections of this Indenture referred to below in this Section 8.2, and
to have satisfied all of their other obligations under such Notes and this
Indenture and cured all then existing Events of Default (and the Trustee, on
demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (a) the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium,
if any, interest, Additional Amounts, if any, and Liquidated Damages, if any, on
such Notes when such payments are due or on the Redemption Date solely out of
the trust created pursuant to this Indenture; (b) the Company's obligations with
respect to Notes concerning issuing temporary Notes, or, where relevant,
registration of such Notes, mutilated, destroyed, lost or stolen Notes and the
maintenance of an office or agency for payment and money for security payments
held in trust; (c) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith; and (d) this
Article VIII and the obligations set forth in Section 8.6 hereof.

       Subject to compliance with this Article VIII, the Company may exercise
its option under Section 8.2 notwithstanding the prior exercise of its option
under Section 8.3 with respect to the Notes.

       SECTION 8.3  Covenant Defeasance.  Upon the Company's exercise under
                    -------------------
Section 8.1 of the option applicable to this Section 8.3, the Company shall be
released from any obligations under the covenants contained in Sections 4.3,
4.4, 4.10, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19, 4.22, 4.23 and 5.1
hereof with respect to the outstanding Notes on and after the date the
conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"),
                                                        -------------------
and the Notes shall thereafter be deemed not "outstanding" for the purposes of
any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term,

                                       67


condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or Event of Default under subsection 6.1(e), nor shall any event referred to in
subsection 6.1(f) or (g) thereafter constitute a Default or Event of Default,
but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby.

     and Liquidated Damages, if any, due on the outstanding Notes on the stated

     assumptions and exclusions, the Holders of the outstanding Notes will not
     recognize income, gain or loss for U.S. federal income tax purposes as a
     result of such Legal Defeasance and will be subject to U.S. federal income

     Legal Defeasance had not occurred and (2) payments from the defeasance
     trust will be free and exempt from any and all withholding and other income

     Trustee has a perfected security interest in such trust funds for the
     ratable benefit of the Holders;

       (vii) the Company shall have delivered to the Trustee an Officers'

respect to such trust money, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company give notice to the Holders or cause to be
published notice once, in a leading newspaper having a general circulation in
New York (which is expected to be The Wall Street Journal) and in Frankfurt
(which is expected to be the Frankfurter Allgemeine Zeitung) (and, if and so
long as the Notes are listed on the Luxembourg Stock Exchange and the rules of
such stock exchange shall so require, a newspaper having a general circulation
in Luxembourg (which is expected to be the Luxemburger Wort)) or in the case of
Definitive Notes, mail to Holders by first-class mail, postage prepaid, at their
respective addresses as they appear on the registration books of the Registrar

and the rules of such Stock Exchange shall so require, publish in a newspaper
having a general circulation in Luxembourg (which is expected to be the
Luxemburger Wort)), that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification, any unclaimed balance of such money then remaining will be repaid
to the Company.

       SECTION 8.10  Reinstatement.  If the Trustee or Paying Agent is unable to
                     -------------
apply any cash or Government Securities, as applicable, in accordance with
Section 8.2, 8.3, 8.4 or 8.5 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.2, 8.3, 8.4 or 8.5 until such time as
the Trustee or Paying Agent is permitted to apply all such cash or Government
Securities in accordance with Section 8.2, 8.3, 8.4 or 8.5; provided, however,
that if the Company has made any payment of interest on, premium, if any,
principal, Additional Amounts, if any, and Liquidated Damages, if any, of any
Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money or Government Securities, as applicable, held by the Trustee or
Paying Agent.

                                  ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS
                      -----------------------------------

       SECTION 9.1  Without Consent of Holders of Notes.  Notwithstanding
                    -----------------------------------
Section 9.2 hereof, the Company and the Trustee together may amend or supplement
this Indenture or the Notes without the consent of any Holder of a Note (i) to
cure any ambiguity, omission, defect or

                                       71


inconsistency, (ii) to provide for uncertificated Notes in addition to or in
place of certificated Notes, or to provide for additional forms of global Notes
containing transfer and other restrictions and which comply with applicable U.S.
securities and other laws, (iii) to comply with the covenant relating to
mergers, consolidations and sales of assets, (iv) to provide for the assumption
of the Company's obligations to Holders of such Notes, (v) to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under this Indenture of any
such Holder, (vi) to add covenants for the benefit of the Holders or to
surrender any right or power conferred upon the Company, (vii) to comply with
requirements of the Commission in order to effect or maintain the qualification
of this Indenture under the TIA, or (viii) to execute and deliver any documents
necessary or appropriate to release Liens on any Collateral as permitted by the
Collateral Agreement.

       Upon the request of the Company, accompanied by a Board Resolution
authorizing the execution of any such amendment or supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 9.6, the
Trustee shall join with the Company in the execution of any amended or
supplemental indenture authorized or permitted by the terms of this Indenture
and to make any further appropriate agreements and stipulations which may be
therein contained, but the Trustee shall not be obligated to enter into such
amended or supplemental indenture which adversely affects its own rights, duties
or immunities hereunder or otherwise.

       SECTION 9.2  With Consent of Holders of Notes.  The Company and the
                    --------------------------------
Trustee may amend or supplement this Indenture or the Notes or any amended or
supplemental indenture with the written consent of the Holders of at least a
majority in principal amount of the Notes then outstanding (including consents
obtained in connection with a tender offer or exchange offer for the Notes), and
any existing Default or Event of Default and its consequences or compliance with
any provision of this Indenture or the Notes may be waived with the consent of
the Holders of at least a majority in principal amount of the Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange offer for the Notes).  However, without the consent of each Holder
affected, an amendment or waiver may not (with respect to any Notes held by a
nonconsenting Holder of Notes):  (i) reduce the principal amount of the Notes
whose Holders must consent to an amendment, supplement or waiver, (ii) reduce
the principal of or change the fixed maturity of any such Note or alter or waive
the provisions with respect to the redemption of the Notes, (iii) reduce the
rate of or change the time for payment of interest on any Note, (iv) waive a
Default in the payment of principal of, or premium, if any, interest, Additional
Amounts or Liquidated Damages, if any, on, the Notes (except a rescission of
acceleration of the Notes by the Holders of at least a majority in aggregate
principal amount of the Notes and a waiver of the payment default that resulted
from such acceleration with respect to the Notes) or in respect of a covenant or
provision contained in this Indenture which cannot be amended or modified
without the consent of all Holders, (v) make any Note payable in money other
than that stated in the Notes, (vi) make any change in the provisions of this
Indenture relating to waivers of past Defaults or the rights of Holders of the
Notes to receive payments of principal of, premium, interest, Additional
Amounts, if any, or Liquidated Damages, if any, on, such Notes, (vii) make any
change in the amendment and waiver provisions contained in this Indenture,
(viii) make any change in paragraph 3 of the Initial Notes or paragraph 2 of the
Exchange Notes that adversely affects the rights of any Holder of the Notes,
(ix) amend the terms of the Notes or

                                       72


this Indenture in a way that would result in the loss of an exemption from any
Taxes or an exemption from any obligation to withhold or deduct Taxes unless the
Company agrees to pay Additional Amounts, if any, in respect thereof, (x) modify
the provisions of the Collateral Agreement or this Indenture relating to the
Collateral in any manner adverse to the Holders or release the Collateral from
the Lien under the Collateral Agreement or permit any other obligation to be
secured by the Collateral or (xi) impair the right of any Holder of the Notes to
receive payment of principal of, interest and Liquidated Damages, if any, on,
such Holder's Notes on or after the due dates therefor or to institute suit for
the enforcement of any payment on or with respect to such Holder's Notes.

       Upon the request of the Company, accompanied by a Board Resolution
authorizing the execution of any such amended or supplemental indenture, and
upon the filing with the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of
the documents described in Section 9.6, the Trustee shall join with the Company
in the execution of such amended or supplemental indenture unless such amended
or supplemental indenture adversely affects the Trustee's own rights, duties or
immunities hereunder or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such amended or
supplemental indenture.

       It shall not be necessary for the consent of the Holders of Notes under
this Section 9.2 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

       After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver.  Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver.

       SECTION 9.3  Compliance with TIA.  From the date on which this Indenture
                    -------------------
is qualified under the TIA, every amendment, waiver or supplement of this
Indenture or the Notes shall comply with the TIA as then in effect.

       SECTION 9.4  Revocation and Effect of Consents.  Until an amendment,
                    ---------------------------------
supplement or waiver becomes effective, a consent to it by a Holder of a Note is
a continuing consent by the Holder of a Note and every subsequent Holder of a
Note or portion of a Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on any Note.
However, any such Holder of a Note or subsequent Holder of a Note may revoke the
consent as to its Note if the Trustee receives written notice of revocation
before the date the waiver, supplement or amendment becomes effective.  An
amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder of a Note.

       The Company may fix a record date for determining which Holders of the
Notes must consent to such amendment, supplement or waiver.  If the Company
fixes a record date, the record date shall be fixed at (i) the later of 30 days
prior to the first solicitation of such consent or

                                       73


the date of the most recent list of Holders of Notes furnished to the Trustee
prior to such solicitation pursuant to Section 2.5 or (ii) such other date as
the Company shall designate.

       SECTION 9.5  Notation on or Exchange of Notes.  The Trustee may place an
                    --------------------------------
appropriate notation about an amendment, supplement or waiver on any Note
thereafter authenticated.  The Company in exchange for all Notes may issue and
the Trustee shall authenticate new Notes that reflect the amendment, supplement
or waiver.

       Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

       SECTION 9.6  Trustee to Sign Amendments, etc.  The Trustee shall execute
                    -------------------------------
any amendment, supplement or waiver authorized pursuant to this Article IX;
provided, however, that the Trustee may, but shall not be obligated to, execute
any such amendment, supplement or waiver which adversely affects the Trustee's
own rights, duties or immunities under this Indenture.  The Trustee shall be
entitled to receive indemnity reasonably satisfactory to it, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
each stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article IX is authorized or permitted by this
Indenture and constitutes the legal, valid and binding obligations of the
Company enforceable in accordance with its terms.  Such Opinion of Counsel shall
not be an expense of the Trustee.

performance of all other obligations of the Company to the Holders of such Notes
or the Trustee under this Indenture with respect to such Notes, and each of the
Notes, according to the terms hereunder or thereunder, shall be secured as
provided in the Collateral Agreement which the Company, the Collateral Agent and
the Trustee have entered into simultaneously with the execution of this
Indenture.  Each Holder of each Note, by its acceptance thereof, consents and
agrees to the terms of the Collateral Agreement (including, without limitation,
the provisions providing for foreclosure and disbursement of Collateral) as the
same may be in effect or may be amended from time to time in accordance with its
terms and authorizes and directs the Collateral Agent and the Trustee to enter
into the Collateral Agreement and to perform its obligations and exercise its
rights thereunder in accordance therewith.  The Company shall deliver to the
Trustee copies of the Collateral Agreement, and shall do or cause to be done all
such acts and things as may be necessary or proper, or as may be required by the
provisions of the Collateral Agreement, to assure and confirm to the Trustee
(acting on behalf of the Holders of the Notes) the security interest in the
Collateral with respect to the Notes contemplated by the Collateral Agreement or
any part thereof, as from time to time constituted, so as to render the same
available for the security and benefit of this Indenture with respect to, and
of, such Notes, according to the intent

                                       74

and all actions reasonably required to cause the Collateral Agreement to create
and maintain (to the extent possible under applicable law), as security for the
obligations of the Company hereunder, a valid and enforceable perfected first
priority Lien in and on all the Collateral with respect to the Notes, in favor
of the Trustee (acting on behalf of the Holders of the Notes) for the benefit of
the Holders of such Notes, superior to and prior to the rights of all third
Persons and subject to no other Liens.

       SECTION 10.2 Recording and Opinions.  (a)  The Company shall furnish to
                    ----------------------
the Trustee simultaneously with the execution and delivery of this Indenture an
Opinion of Counsel stating that, in the opinion of such counsel, either (i) all
action has been taken with respect to the recording, registering and filing of
this Indenture, financing statements or other instruments necessary to make
effective the Lien intended to be created by the Collateral Agreement, and
reciting with respect to the security interests in the Collateral, the details
of such action, or (ii) no such action is necessary to make such Lien effective.

       (b) The Company shall furnish to the Collateral Agent and the Trustee

which the balance of Available Funds (as defined in the Collateral Agreement)
shall have been reduced to zero, an Opinion of Counsel, dated as of such date,
either (i) stating that (A) in the opinion of such counsel, action has been
taken with respect to the recording, registering, filing, re-recording, re-
registering and refiling of all supplemental indentures, financing statements,

necessary, if any, to maintain the Lien of the Collateral Agreement and reciting
with respect to the security interests in the Collateral the details of such
action or referring to prior Opinions of Counsel in which such details are given
and (B) based on relevant laws as in effect on the date of such Opinion of
Counsel, all financing statements and continuation statements have been executed
and filed that are necessary as of such date and during the succeeding 12 months

are possible by filing, the rights of the Holders of the Notes and the Trustee
hereunder and under the Collateral Agreement with respect to the security
interests in the Collateral with respect to such Notes or (ii) stating that, in
the opinion of such counsel, no such action is necessary to maintain such Lien
and assignment.

       SECTION 10.3 Release of Collateral.  (a)  Subject to subsections (b), (c)
                    ---------------------
and (d) of this Section 10.3, Collateral may be released from the Lien and
security interest created by the Collateral Agreement only in accordance with
the provisions of the Collateral Agreement.

       (b) Except to the extent that any Lien on proceeds of Collateral is
automatically released by operation of Section 9-306 of the Uniform Commercial
Code or other similar law, no Collateral shall be released from the Lien and
security interest created by the Collateral Agreement pursuant to the provisions
of the Collateral Agreement, other than pursuant to the terms thereof, unless
there shall have been delivered to the Trustee the certificate required by
Section 10.3(d) and Section 10.4.

       (c) At any time when an Event of Default shall have occurred and be
continuing and the maturity of the Notes issued on the Issuance Date shall have
been accelerated (whether by

                                       75


declaration or otherwise), no Collateral shall be released pursuant to the
provisions of the Collateral Agreement, and no release of Collateral in
contravention of this Section 10.3(c) shall be effective as against the Holders
of Notes, except for the disbursement of all Available Funds (as defined in the
Collateral Agreement) to the Trustee pursuant to Section 6(c) of the Collateral
Agreement.

       (d) The release of any Collateral from the Liens and security interests
created by the Collateral Agreement shall not be deemed to impair the security
under the Collateral Agreement in contravention of the provisions hereof if and
to the extent the Collateral is released pursuant to the terms hereof or,
subject to complying with the requirements of this Section 10.3, and Section
10.4 pursuant to the terms of the Collateral Agreement.  To the extent
applicable, the Company shall cause Section 314(d) of the TIA relating to the
release of property or securities from the Lien and security interest of the
Collateral Agreement to be complied with.  Any certificate or opinion required
by Section 314(d) of the TIA may be made by an Officer of the Company except in
cases where Section 314(d) of the TIA requires that such certificate or opinion
be made by an independent Person, which Person shall be an independent engineer,
appraiser or other expert selected by the Company.

       SECTION 10.4 Certificates of the Company.  The Company shall furnish to
                    ---------------------------
the Trustee, prior to any proposed release of the Collateral other than pursuant
to the express terms of the Collateral Agreement, (i) all documents required by
Section 314(d) of the TIA and (ii) an Opinion of Counsel, which may be rendered
by internal counsel to the Company, to the effect that such accompanying
documents constitute all documents required by Section 314(d) of the TIA.  The
Trustee may, to the extent permitted by Sections 7.1 and 7.2, accept as
conclusive evidence of compliance with the foregoing provisions the appropriate
statements contained in such documents and such Opinion of Counsel.

       SECTION 10.5 Authorization of Actions to Be Taken by the Trustee Under
                    ---------------------------------------------------------

Holders of such Notes, take all actions as so directed in order to (a) enforce
any of the terms of the Collateral Agreement and (b) collect and receive any and
all amounts payable in respect of the obligations of the Company hereunder.  The
Trustee shall have power to institute and maintain such suits and proceedings as
directed to prevent any impairment of the Collateral by any acts that may be
unlawful or in violation of the Collateral Agreement or this Indenture, and to
preserve or protect its interests and the interests of the Holders of the Notes
in the Collateral with respect to such Notes (including power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with
any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with,
such enactment, rule or order would impair the security interest hereunder or be
prejudicial to the interests of the Holders of such Notes or of the Trustee).

Agreement upon the Company's compliance with the provisions of the TIA
pertaining to release of collateral.

       The Trustee shall not be responsible for filing any financing or
continuation statements or recording any documents or instruments in any public
office at any time or times or otherwise perfecting or maintaining the
perfection of any security interest in the Collateral.

value of any of the Collateral or for the validity, perfection, priority or
enforceability of the Liens in any of the Collateral, whether impaired by
operation of law or by reason of any action or omission to act on its part
hereunder, except to the extent such action or omission constitutes gross
negligence, bad faith or willful misconduct on the part of the Trustee, for the

       SECTION 11.9  Submission to Jurisdiction; Appointment of Agent for
                     ----------------------------------------------------
Service; Waiver.  To the fullest extent permitted by applicable law, the Company
- ---------------
irrevocably submits to the non-exclusive jurisdiction of any federal or state
court in the Borough of Manhattan in The City of New York, County and State of
New York, United States of America, in any suit or proceeding based on or
arising under this Indenture and the Notes, and irrevocably agrees that all
claims in respect of such suit or proceeding may be determined in any such
court.  The Company, to the fullest extent permitted by applicable law,
irrevocably and fully waives the defense of an inconvenient forum to the
maintenance of such suit or proceeding and hereby irrevocably designates and
appoints CSC (the "Authorized Agent"), for a period of ten years from the date
                   ----------------
hereof or until such time as no Notes are outstanding, as its authorized agent
upon whom process may be served in any such suit or proceeding.  The Company
represents that it has notified the Authorized Agent of such designation and
appointment and that the Authorized Agent has accepted the same in writing.  The
Company hereby irrevocably authorizes and directs its Authorized Agent to accept
such service.  The Company further agrees that service of process upon its
Authorized Agent and written notice of said service to the Company mailed by
first class mail or delivered to its Authorized Agent shall be deemed in every
respect effective service of process upon the Company in any such suit or
proceeding.  Nothing herein shall affect the right of any person to serve
process in any other manner permitted by law.  The Company agrees that a final
action in any such suit or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other lawful manner.
Notwithstanding the foregoing, any action against the Company arising out of or
based on this Indenture, the Notes or the transactions contemplated hereby may
also be instituted in any competent court in Germany, and the Company expressly
accepts the jurisdiction of any such court in any such action.

      The Company hereby irrevocably waives, to the extent permitted by law, any
immunity to jurisdiction to which it may otherwise be entitled (including,
without limitation, immunity to pre-judgment attachment, post-judgment
attachment and execution) in any legal suit, action or proceeding against it
arising out of or based on this Indenture, the Notes or the transactions
contemplated hereby.

      To the extent permitted by applicable law, the Company and the Trustee
each waive any right to have a jury participate in resolving any dispute,
whether sounding in contract, tort, or otherwise arising out of, connected with,
related to or incidental to the relationship established between them in
connection with this agreement.  Instead, any disputes resolved in court will be
resolved in a bench trial without a jury.

                                       80


      The provisions of this Section 11.9 are intended to be effective upon the
execution of this Indenture and the Notes without any further action by the
Company or the Trustee and the introduction of a true copy of this Indenture
into evidence shall be conclusive and final evidence as to such matters.

       SECTION 11.10  No Adverse Interpretation of Other Agreements.  This
                      ---------------------------------------------
Indenture may not be used to interpret another indenture, loan or debt agreement
of any of the Company or any of its Subsidiaries.  Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.

       SECTION 11.11  No Personal Liability of Directors, Officers, Employees,
                      --------------------------------------------------------
Stockholders or Incorporators.  No director, officer, employee, incorporator or
- -----------------------------
stockholder of the Company shall have any liability for any obligations of the
Company under the Notes or this Indenture or for any claim based on, in respect
of, or by reason of such obligations or their creation.  Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes.

       SECTION 11.12  Currency Indemnity.  U.S. dollars are the sole currency of
                      ------------------
account and payment for all sums payable by the Company under or in connection
with the Notes, including damages.  Any amount received or recovered in a
currency other than U.S. dollars (whether as a result of, or the enforcement of,
a judgment or order of a court of any jurisdiction, in the winding-up or
dissolution of the Company or otherwise) by any Holder of a Note, the Trustee or
the Agents in respect of any sum expressed to be due to it from the Company
shall only constitute a discharge to the Company to the extent of the U.S.
dollar amount which the recipient is able to purchase with the amount so
received or recovered in that other currency on the date of that receipt or
recovery (or, if it is not practicable to make that purchase on that date, on
the first date on which it is practicable to do so).  If that U.S. dollar amount
is less than the U.S. dollar amount expressed to be due to the recipient, the
Company shall indemnify it against any loss sustained by it as a result. If the
dollar amount is greater than the dollar amount expressed to be due to the
recipient under this Agreement, the Company shall be entitled to the amount of
such excess.  In any event, the Company shall indemnify the recipient against
the cost of making any such purchase. For the purposes of this subsection, it
will be sufficient for the Trustee or any Holder of a Note to certify in a
satisfactory manner (indicating the sources of information used) that it would
have suffered a loss had an actual purchase of U.S. dollars been made with the
amount so received in that other currency on the date of receipt or recovery
(or, if a purchase of dollars on such date had not been practicable, on the
first date on which it would have been practicable, it being required that the
need for a change of date be certified in the manner mentioned above).  These
indemnities constitute a separate and independent obligation from the Company's
other obligations, shall give rise to a separate and independent cause of
action, shall apply irrespective of any indulgence granted by the Trustee or any
Holder of a Note and shall continue in full force and effect despite any other
judgment, order, claim or proof for a liquidated amount in respect of any sum
due under any Note.

       SECTION 11.13  Successors. All agreements of the Company in this
                      ----------
Indenture and the Notes shall bind its successors. All agreements of the Trustee
in this Indenture shall bind its successor.

                                       81


       SECTION 11.14  Counterpart Originals  All parties hereto may sign any
                      ---------------------
number of copies of this Indenture.  Each signed copy or counterpart shall be an
original, but all of them together shall represent one and the same agreement.

       SECTION 11.15  Severability.  In case any one or more of the provisions
                      ------------
in this Indenture or in the Notes shall be held invalid, illegal or
unenforceable, in any respect for any reason, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions shall not in any way be affected or impaired thereby, it being
intended that all of the provisions hereof shall be enforceable to the full
extent permitted by law.

       SECTION 11.16  Table of Contents, Headings, etc.  The Table of Contents,
                      --------------------------------
Cross-Reference Table and Headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be
considered a part of this Indenture and shall in no way modify or restrict any
of the terms or provisions hereof.

      IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be

Dated:  July 8, 1999

                                      A-5


                               [FORM OF REVERSE]

                CYBERNET INTERNET SERVICES INTERNATIONAL, INC.

                          14.0% Senior Note due 2009


     1.  Interest. CYBERNET INTERNET SERVICES INTERNATIONAL, INC., a Delaware
         --------
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at the rate and in the manner specified below. Interest on the Notes
will accrue at 14.0% per annum on the principal amount then outstanding, and be
payable semi-annually in arrears on each January 1 and July 1, or if any such
day is not a Business Day on the next succeeding Business Day, commencing
January 1, 2000, to the Holder hereof. Notwithstanding any exchange of this Note
for a Definitive Note during the period starting on a Record Date relating to
such Definitive Note and ending on the immediately succeeding Interest Payment
Date, the interest due on such Interest Payment Date shall be payable to the
Person in whose name this Global Note is registered at the close of business on
the Record Date for such interest. Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from July 8, 1999. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     The Company shall pay interest on overdue principal and on overdue
installments of interest (without regard to any applicable grace periods), on
any Additional Amounts, and on any Liquidated Damages, from time to time on
demand at the rate borne by the Notes plus 1.5% per annum to the extent lawful.
Any interest paid on this Note shall be increased to the extent necessary to pay
Additional Amounts as set forth herein.

     2.  Liquidated Damages.  Pursuant to a Registration Rights Agreement
         ------------------
between the Company and the Initial Purchasers on behalf of Holders of the
Initial Notes, the Company has agreed to use its reasonable best efforts to
consummate an exchange offer pursuant to which the Holder of this Note shall
have the right to exchange this Note for the Company's 14.0% Senior Notes due
2009 (the "Exchange Notes"), which have then been registered under the
Securities Act, in like principal amount and having substantially identical
terms in all material respects as the Initial Notes.  The Holders shall be
entitled to receive payment of additional interest ("Liquidated Damages") in the
event such exchange offer is not consummated and in certain other events,
subject, in each case, to certain conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.  Liquidated Damages which
may be payable pursuant to the Registration Rights Agreement shall be payable in
the same manner as set forth herein with respect to the stated interest.  The
provisions of the Registration Rights Agreement relating to such Liquidated
Damages are incorporated herein by reference and made a part hereof as if set
forth herein in full.  The Company shall provide written notice to the Trustee
of the accrual and amount of Liquidated Damages, if any, not less than ten (10)
Business Days prior to each Interest Payment Date.  Absent such notice, the
Trustee shall be conclusively entitled to presume that no Liquidated Damages
have accrued and are owing.

     3.  Additional Amounts.  All payments made by the Company on the Notes
         ------------------
(whether or not in the form of Definitive Notes) will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever

                                      A-6


nature (collectively, "Taxes") imposed or levied by or on behalf of Germany or
any jurisdiction in which the Company or any Surviving Entity is organized or is
otherwise resident for tax purposes or any political subdivision thereof or any
authority having power to tax therein or any jurisdiction from or through which
payment is made (each a "Relevant Taxing Jurisdiction"), unless the withholding
or deduction of such Taxes is then required by law. If any deduction or
withholding for, or on account of, any Taxes of any Relevant Taxing
Jurisdiction, shall at any time be required on any payments made by the Company
with respect to the Notes, including payments of principal, redemption price,
interest or premium, the Company will pay such additional amounts (the
"Additional Amounts") as may be necessary in order that the net amounts received
in respect of such payments by the Holders of the Notes or the Trustee, as the
case may be, after such withholding or deduction, equal the respective amounts
which would have been received in respect of such payments in the absence of
such withholding or deduction; except that no such Additional Amounts will be
payable with respect to:

          (a)  any payments on a Note held by or on behalf of a Holder or
     beneficial owner who is liable for such Taxes in respect of such Note by
     reason of the Holder or beneficial owner having some connection with the
     Relevant Taxing Jurisdiction (including being a citizen or resident or
     national of, or carrying on a business or maintaining a permanent
     establishment in, or being physically present in, the Relevant Taxing
     Jurisdiction) other than by the mere holding of such Note or enforcement of
     rights thereunder or the receipt of payments in respect thereof;

          (b)  any Taxes that are imposed or withheld as a result of a change in
     law after the Issue Date where such withholding or imposition is by reason
     of the failure of the Holder or beneficial owner of the Note to comply with
     any request by the Company to provide information concerning the
     nationality, residence or identity of such Holder or beneficial owner or to
     make any declaration or similar claim or satisfy any information or
     reporting requirement, which is required or imposed by a statute, treaty,
     regulation or administrative practice of the Relevant Taxing Jurisdiction
     as a precondition to exemption from all or part of such Taxes;

          (c)  except in the case of the winding up of the Company, any Note
     presented for payment (where presentation is required) in the Relevant
     Taxing Jurisdiction; or

          (d)  any Note presented for payment (where presentation is required)
     more than 30 days after the relevant payment is first made available for
     payment to the Holder.

          Such Additional Amounts will also not be payable where, had the
beneficial owner of the Note been the Holder of the Note, he would not have been
entitled to payment of Additional Amounts by reason of clauses (a) to (d)
inclusive above.

          4.  Method of Payment.  The Company shall pay interest on the Notes
              -----------------
(except defaulted interest) to the Person in whose name this Note is registered
at the close of business on the Record Date for such interest.  Holders must
surrender Notes to a Paying Agent to collect principal payments.  The Company
shall pay principal and interest in dollars or in such other coin or currency of
the United States of America that at the time of payment which is legal tender
for payment of public and private debts.  Immediately available funds for the
payment of the principal of (and

                                      A-7


premium, if any), interest, Additional Amounts, if any, and Liquidated Damages,
if any, on this Note due on any Interest Payment Date, Maturity Date, Redemption
Date or other repurchase date will be made available to the Paying Agent to
permit the Paying Agent to pay such funds to the Holders on such respective
dates.

          5.  Paying Agent and Registrar.  Initially, The Bank of New York will
              --------------------------
act as Paying Agent and Registrar.  The Company may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders.  The Company or any of
its Subsidiaries may, subject to certain exceptions, act in any such capacity.

          6.  Indenture.  The Company issued the Notes under an Indenture, dated
              ---------
as of July 8, 1999 (the "Indenture"), between the Company and The Bank of New
York (the "Trustee"). This Note is one of a duly authorized issue of [Original]
[Additional] Notes (as defined in the Indenture) of the Company designated as
its 14.0% Senior Notes due 2009 (together with the [Original] [Additional]
Notes, the "Initial Notes"). The Notes include the Initial Notes and the
Exchange Notes issued in exchange for the Initial Notes pursuant to the
Indenture. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in effect on the date of
the Indenture until such time as the Indenture is qualified under the TIA, and
thereafter as in effect on the date on which the Indenture is qualified under
the TIA. Notwithstanding anything to the contrary herein, the Notes are subject
to all such terms, and Holders of Notes are referred to the Indenture and the
TIA for a statement of them. The Notes are not secured by any of the assets of
the Company except to the limited extent provided for by the Collateral
Agreement, and will become general unsecured obligations of the Company upon
disbursement in full of the funds in the Collateral Account. The Notes are
limited in aggregate principal amount to $350 million subject to the terms of
the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of
the terms and provisions of the Indenture, as the same may be amended from time
to time.

          7.  Ranking.  The Notes will be general unsecured (except to the
              -------
extent provided for by the Collateral Agreement) obligations of the Company and
will rank senior in right of payment to all future Indebtedness of the Company
that is, by its terms or by the terms of the agreement or instrument governing
such Indebtedness, expressly subordinated in right of payment to the Notes and
pari passu in right of payment with all existing and future unsecured
liabilities of the Company that are not so subordinated.

          8.  Optional Redemption.  The Notes will be redeemable, at the
              --------------------
Company's option, in whole or in part, on and after July 1, 2004 upon not less
than 30 nor more than 60 days' prior notice published in a leading newspaper
having a general circulation in New York (which is expected to be The Wall
Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allgemeine Zeitung) (and if, and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
published in a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)) at the redemption prices (expressed as a
percentage of principal amount) set forth below, plus accrued and unpaid
interest, Additional Amounts, if any, and Liquidated Damages, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on July 1 of each of the years indicated below:

2006...................................................   103.333%
2007 and thereafter....................................   100.000%


          9.  Special Tax Redemption.  The Notes may be redeemed, at the option
              ----------------------
of the Company in whole but not in part, at any time upon giving not less than
30 nor more than 60 days' notice to the Holders (which notice shall be
irrevocable), at a redemption price equal to the principal amount thereof,
together with accrued and unpaid interest and Liquidated Damages, if any,  to
the date fixed by the Company for redemption (a "Tax Redemption Date"), and, all
Additional Amounts, if any, then due and which will become due on the Tax
Redemption Date as a result of the redemption or otherwise, if the Company
determines that, as a result of (i) any change in, or amendment to, the laws or
treaties (or any regulations or rulings promulgated thereunder) of The Federal
Republic of Germany (or any political subdivision or taxing authority thereof)
affecting taxation which becomes effective on or after the Issue Date, or (ii)
any change in or new or different position regarding the application,
administration or interpretation of such laws, treaties, regulations or rulings
(including a holding, judgment or order by a court of competent jurisdiction),
which change, amendment, application or interpretation becomes effective on or
after the Issue Date, the Company is, or on the next Interest Payment Date would
be, required to pay Additional Amounts, and the Company determines that such
payment obligation cannot be avoided by the Company taking reasonable measures.
Notwithstanding the foregoing, no such notice of redemption shall be given
earlier than 90 days prior to the earliest date on which the Company would be
obligated to make such payment or withholding if a payment in respect of the
Notes were then due. Prior to the publication or, where relevant, mailing of any
notice of redemption of the Notes pursuant to the foregoing, the Company will
deliver to the Trustee an opinion of an independent tax counsel of recognized
international standing to the effect that the circumstances referred to above
exist. The Trustee shall accept such opinion as sufficient evidence of the
satisfaction of the conditions precedent described above, in which event it
shall be conclusive and binding on the Holders.

          10.  Notice of Redemption.  Notice of redemption will be given at
               --------------------
least 30 days but not more than 60 days before the redemption date by publishing
in a leading newspaper having a general circulation in New York (which is
expected to be The Wall Street Journal) and in Frankfurt (which is expected to
be the Frankfurter Allgemeine Zeitung) (and, if and so long as the Notes are
listed on the Luxembourg Stock Exchange and the rules of such stock exchange
shall so require, a newspaper having a general circulation in Luxembourg (which
is expected to be the Luxemburger Wort)).  Notes in denominations of $1,000 may
be redeemed only in whole.  The Trustee may select for redemption portions
(equal to $1,000 or any integral multiple thereof) of the principal of Notes
that have denominations larger than $1,000.

          Except as set forth in the Indenture, from and after any redemption
date, if monies for the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such redemption date,
then, unless the Company defaults in the payment of such Redemption Price, the
Notes called for redemption will cease to bear interest, Additional

                                      A-9


Amounts, if any, or Liquidated Damages, if any, and the only right of the
Holders of such Notes will be to receive payment of the Redemption Price.

          11.  Change of Control Offer.  Upon the occurrence of a Change of
               -----------------------
Control, the Company will be required to make an offer to purchase all or any
part (equal to $1,000 in principal amount and integral multiples thereof) of the
Notes on the Change of Control Payment Date at a purchase price in cash equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest,
thereon to the date of repurchase plus Additional Amounts, if any, and
Liquidated Damages, if any, to the date of repurchase. Holders of Notes that are
subject to an offer to purchase will receive a Change of Control Offer from the
Company prior to any related Change of Control Payment Date and may elect to
have such Notes purchased by completing the form entitled "Option of Holder to
Elect Purchase" appearing below.

          12.  Limitation on Disposition of Assets.  When the aggregate amount
               -----------------------------------
of Excess Proceeds from Asset Sales exceeds C5.0 million, the Company will be
obligated, within 15 Business Days thereafter, to make an offer to purchase the
maximum principal amount of Notes, that is an integral multiple of $1,000, that
may be purchased out of the Excess Proceeds at an offer price in cash in an
amount equal to 100% of the aggregate principal amount thereof, plus accrued and
unpaid interest thereon, plus Additional Amounts, if any, and Liquidated
Damages, if any, to the date fixed for the closing of such offer.  If the
aggregate principal amount of Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, subject to applicable law, the Trustee shall select
the Notes to be redeemed in accordance with the Indenture; provided, however,
that no Notes of $1,000 or less shall be purchased in part.  Holders of Notes
that are the subject of an offer to purchase will receive an Asset Sale Offer
from the Company prior to any related purchase date and may elect to have such
Notes purchased by completing the form entitled "Option of Holders to Elect
Purchase" appearing below.

          13.  Denominations; Form.  The Global Notes are in registered global
               -------------------

               ---------------------
be treated as the owner of it for all purposes, subject to the terms of the
Indenture.

          15.  Unclaimed Funds.  If funds for the payment of principal,
               ---------------
interest, Additional Amounts or Liquidated Damages remain unclaimed for two
years, the Trustee and the Paying Agents will repay the funds to the Company at
its written request.  After that, all liability of the Trustee and such Paying
Agents with respect to such funds shall cease.

          16.  Legal Defeasance and Covenant Defeasance.  The Company may be
               ----------------------------------------
discharged from its obligations under the Indenture and the Notes except for
certain provisions thereof ("Legal Defeasance"), and may be discharged from its
obligations to comply with certain covenants contained in the Indenture
("Covenant Defeasance"), in each case upon satisfaction of certain conditions
specified in the Indenture.

          17.  Amendment; Supplement; Waiver.  Subject to certain exceptions
               -----------------------------
specified in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of at least a majority in
principal amount of the Notes then outstanding, and any existing

                                     A-10


Default or Event of Default or compliance with any provision of the Indenture or

Subsidiaries to, incur additional Indebtedness, pay dividends or make other
distributions or investments, repurchase Equity Interests or make certain other
Restricted Payments, enter into certain consolidations or mergers or enter into
certain transactions with Affiliates and consummate certain mergers and
consolidations or sales of all or substantially all assets.  The limitations are
subject to a number of important qualifications and exceptions.  The Company
must annually report to the Trustee on compliance with such limitations.

          19.  Successors.  When a successor assumes all the obligations of its
               ----------
predecessor under the Notes and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          20.  Defaults and Remedies.  If an Event of Default (other than an
               ---------------------
Event of Default specified in subsections 6.1(h) or (i) of the Indenture) occurs
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately in the manner and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture or the Notes except as provided
in the Indenture. The Trustee is not obligated to enforce the Indenture or the
Notes unless it has received indemnity satisfactory to it.  The Indenture
permits, subject to certain limitations therein provided, Holders of a majority
in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power.  The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal, premium,  interest, Additional Amounts, if any,
and Liquidated Damages, if any, including an accelerated payment) if it
determines that withholding notice is in their interest.

          21.  Trustee Dealings with Company.  The Trustee under the Indenture,
               -----------------------------
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          22.  No Recourse Against Others.  No stockholder, director, officer,
               --------------------------
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder of the Notes by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          23.  Authentication.  This Note shall not be valid until the Trustee
               --------------
or authenticating agent signs the certificate of authentication on this Note.

Initial Notes, the Company has agreed to use its reasonable best efforts to
consummate an exchange offer pursuant to which the Holder of this Note shall
have the right to exchange this Note for the Company's 14.0% Senior Notes due
2009 (the "Exchange Notes"), which have then been registered under the
Securities Act, in like principal amount and having substantially identical
terms in all material respects as the Initial Notes.  The Holders shall be
entitled to receive payment of additional interest ("Liquidated Damages") in the
event such exchange offer is not consummated and in certain other events,
subject, in each case, to certain conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.  Liquidated Damages which
may be payable pursuant to the Registration Rights Agreement shall be payable in
the same manner as set forth herein with respect to the stated interest.  The
provisions of the Registration Rights Agreement relating to such Liquidated
Damages are incorporated herein by reference and made a part hereof as if set
forth herein in full.  The Company shall provide written notice to the Trustee
of the accrual and amount of Liquidated Damages, if any, not less than ten (10)
Business Days prior to each Interest Payment Date.  Absent such notice, the
Trustee shall be conclusively entitled to presume that no Liquidated Damages
have accrued and are owing.

          3.  Additional Amounts.  All payments made by the Company on the Notes
              ------------------
(whether or not in the form of Definitive Notes) will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, assessments, or governmental charges of whatever nature (collectively,
"Taxes") imposed or levied by or on behalf of Germany or any

                                      B-5


jurisdiction in which the Company or any Surviving Entity is organized or is
otherwise resident for tax purposes or any political subdivision thereof or any
authority having power to tax therein or any jurisdiction from or through which
payment is made (each a "Relevant Taxing Jurisdiction"), unless the withholding
or deduction of such Taxes is then required by law. If any deduction or
withholding for, or on account of, any Taxes of any Relevant Taxing
Jurisdiction, shall at any time be required on any payments made by the Company
with respect to the Notes, including payments of principal, redemption price,
interest or premium, the Company will pay such additional amounts (the
"Additional Amounts") as may be necessary in order that the net amounts received
in respect of such payments by the Holders of the Notes or the Trustee, as the
case may be, after such withholding or deduction, equal the respective amounts
which would have been received in respect of such payments in the absence of
such withholding or deduction; except that no such Additional Amounts will be
payable with respect to:

          (a)  any payments on a Note held by or on behalf of a Holder or
     beneficial owner who is liable for such Taxes in respect of such Note by
     reason of the Holder or beneficial owner having some connection with the
     Relevant Taxing Jurisdiction (including being a citizen or resident or
     national of, or carrying on a business or maintaining a permanent
     establishment in, or being physically present in, the Relevant Taxing
     Jurisdiction) other than by the mere holding of such Note or enforcement of
     rights thereunder or the receipt of payments in respect thereof;

          (b)  any Taxes that are imposed or withheld as a result of a change in
     law after the Issue Date where such withholding or imposition is by reason
     of the failure of the Holder or beneficial owner of the Note to comply with
     any request by the Company to provide information concerning the
     nationality, residence or identity of such Holder or beneficial owner or to
     make any declaration or similar claim or satisfy any information or
     reporting requirement, which is required or imposed by a statute, treaty,
     regulation or administrative practice of the Relevant Taxing Jurisdiction
     as a precondition to exemption from all or part of such Taxes;

          (c)  except in the case of the winding up of the Company, any Note
     presented for payment (where presentation is required) in the Relevant
     Taxing Jurisdiction; or

          (d)  any Note presented for payment (where presentation is required)
     more than 30 days after the relevant payment is first made available for
     payment to the Holder.

          Such Additional Amounts will also not be payable where, had the
beneficial owner of the Note been the Holder of the Note, he would not have been
entitled to payment of Additional Amounts by reason of clauses (a) to (d)
inclusive above.

          4.  Method of Payment.  The Company shall pay interest on the Notes
              -----------------
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date immediately preceding the Interest Payment
Date for such interest.  Holders must surrender Notes to a Paying Agent to
collect principal payments.  The Company shall pay principal and interest in
dollars or in such other coin or currency of the United States of America at the
time of payment which is legal tender for payment of public and private debts;
provided, however, that with respect to any payment of principal, interest,
Additional Amounts, if any, and

                                      B-6


Liquidated Damages, if any, in excess of C100,000 to any payee or group of
related payees, such payment will be made, at the option of the Holder hereof,
by wire transfer of same day funds to the Paying Agent, who in turn will wire
such funds to the Holder hereof or to such individuals as the Holder hereof may
in writing to the Paying Agent direct; provided that the Paying Agent has
received written wire transfer instructions at least fifteen days prior to the
date of any such payment.

          5.  Paying Agent and Registrar.  Initially, The Bank of New York will
              --------------------------
act as Paying Agent and Registrar.  The Company may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders.  The Company or any of
its Subsidiaries may, subject to certain exceptions, act in any such capacity.

          6.  Indenture.  The Company issued the Notes under an Indenture, dated
              ---------
as of July 8, 1999 (the "Indenture"), between the Company and The Bank of New
York (the "Trustee"). This Note is one of a duly authorized issue of [Original]
[Additional] Notes (as defined in the Indenture) of the Company designated as
its 14.0% Senior Notes due 2009 (together with the [Original] [Additional]
Notes, the "Initial Notes").  The Notes include the Initial Notes and the
Exchange Notes issued in exchange for the Initial Notes pursuant to the
Indenture.  The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in effect on the date of
the Indenture until such time as the Indenture is qualified under the TIA, and
thereafter as in effect on the date on which the Indenture is qualified under
the TIA.  Notwith  standing anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture
and the TIA for a statement of them.  The Notes are not secured by any of the
assets of the Company except to the limited extent provided for by the
Collateral Agreement, and will become general unsecured obligations of the
Company upon disbursement in full of the funds in the Collateral Account.  The
Notes are limited in aggregate principal amount to $350 million subject to the
terms of the Indenture.  Each Holder, by accepting a Note, agrees to be bound by
all of the terms and provisions of the Indenture, as the same may be amended
from time to time.

          7.  Ranking.  The Notes will be general unsecured (except to the
              -------
extent provided for by the Collateral Agreement) obligations of the Company and
will rank senior in right of payment to all future Indebtedness of the Company
that is, by its terms or by the terms of the agreement or instrument governing
such Indebtedness, expressly subordinated in right of payment to the Notes and
pari passu in right of payment with all existing and future unsecured
liabilities of the Company that are not so subordinated.

          8.  Optional Redemption.  The Notes will be redeemable, at the
              --------------------
Company's option, in whole or in part, on and after July 1, 2004 upon not less
than 30 nor more than 60 days' prior notice published in a leading newspaper
having a general circulation in New York (which is expected to be The Wall
Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allgemeine Zeitung) (and if, and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
published in a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)) and mailed by first-class mail to each
Holder's registered address, at the redemption prices (expressed as a percentage
of principal amount) set forth below, plus accrued and unpaid interest,

                                      B-7


Additional Amounts, if any, and Liquidated Damages, if any, to the applicable
redemption date (and, subject to the rights of Holders of record on the relevant
record date to receive interest and Additional Amounts, if any, and Liquidated
Damages, if any, due on the relevant interest payment date in respect thereof),
if redeemed during the twelve-month period beginning on July 1 of each of the
years indicated below:

                                                       Redemption
Year                                                      Price
- ----                                                   ----------
2004.................................................   110.000%
2005.................................................   106.667%
2006.................................................   103.333%
2007 and thereafter..................................   100.000%


          9.  Special Tax Redemption.  The Notes may be redeemed, at the option
              ----------------------
of the Company in whole but not in part, at any time upon giving not less than
30 nor more than 60 days' notice to the Holders (which notice shall be
irrevocable), at a redemption price equal to the principal amount thereof,
together with accrued and unpaid interest and Liquidated Damages, if any, to the
date fixed by the Company for redemption (a "Tax Redemption Date"), and, all
Additional Amounts, if any, then due and which will become due on the Tax
Redemption Date as a result of the redemption or otherwise, if the Company
determines that, as a result of (i) any change in, or amendment to, the laws or
treaties (or any regulations or rulings promulgated thereunder) of The Federal
Republic of Germany (or any political subdivision or taxing authority thereof)
affecting taxation which becomes effective on or after the Issue Date, or (ii)
any change in or new or different position regarding the application,
administration or interpretation of such laws, treaties, regulations or rulings
(including a holding, judgment or order by a court of competent jurisdiction),
which change, amendment, application or interpretation becomes effective on or
after the Issue Date, the Company is, or on the next Interest Payment Date would
be, required to pay Additional Amounts, and the Company determines that such
payment obligation cannot be avoided by the Company taking reasonable measures.
Notwithstanding the foregoing, no such notice of redemption shall be given
earlier than 90 days prior to the earliest date on which the Company would be
obligated to make such payment or withholding if a payment in respect of the
Notes were then due. Prior to the publication or, where relevant, mailing of any
notice of redemption of the Notes pursuant to the foregoing, the Company will
deliver to the Trustee an opinion of an independent tax counsel of recognized
international standing to the effect that the circumstances referred to above
exist. The Trustee shall accept such opinion as sufficient evidence of the
satisfaction of the conditions precedent described above, in which event it
shall be conclusive and binding on the Holders.

          10.  Notice of Redemption.  Notice of redemption will be given at
               --------------------
least 30 days but not more than 60 days before the redemption date by publishing
in a leading newspaper having a general circulation in New York (which is
expected to be The Wall Street Journal) and in Frankfurt (which is expected to
be the Frankfurter Allgemeine Zeitung) (and, if and so long as the Notes are
listed on the Luxembourg Stock Exchange and the rules of such stock exchange
shall so require, a newspaper having a general circulation in Luxembourg (which
is expected to be the Luxemburger Wort)) and mailed to Holders by first-class
mail at their respective addresses as they appear on the registration books of
the Registrar.  Notes in denominations of $1,000 may

                                      B-8


be redeemed only in whole. The Trustee may select for redemption portions (equal
to $1,000 or any integral multiple thereof) of the principal of Notes that have
denominations larger than $1,000.

          Except as set forth in the Indenture, from and after any redemption
date, if monies for the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such redemption date,
then, unless the Company defaults in the payment of such Redemption Price, the
Notes called for redemption will cease to bear interest, Additional Amounts, if
any, or Liquidated Damages, if any, and the only right of the Holders of such
Notes will be to receive payment of the Redemption Price.

          11.  Change of Control Offer.  Upon the occurrence of a Change of
               -----------------------
Control, the Company will be required to make an offer to purchase all or any
part (equal to $1,000 in principal amount and integral multiples thereof) of the
Notes on the Change of Control Payment Date at a purchase price in cash equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest,
thereon to the date of repurchase plus Additional Amounts, if any, and
Liquidated Damages, if any, to the date of repurchase (and subject to the right
of Holders of record on the relevant record date to receive interest and
Liquidated Damages, if any, due on the relevant interest payment date and
Additional Amounts, if any, in respect thereof).  Holders of Notes that are
subject to an offer to purchase will receive a Change of Control Offer from the
Company prior to any related Change of Control Payment Date and may elect to
have such Notes purchased by completing the form entitled "Option of Holder to
Elect Purchase" appearing below.

          12.  Limitation on Disposition of Assets.  When the aggregate amount
               -----------------------------------
of Excess Proceeds from Asset Sales exceeds C5.0 million, the Company will be
obligated, within 15 Business Days thereafter, to make an offer to purchase the
maximum principal amount of Notes, that is an integral multiple of $1,000, that
may be purchased out of the Excess Proceeds at an offer price in cash in an
amount equal to 100% of the aggregate principal amount thereof, plus accrued and
unpaid interest thereon, plus Additional Amounts, if any, and Liquidated
Damages, if any, to the date fixed for the closing of such offer (and subject to
the right of Holders of record on the relevant record date to receive interest
and Liquidated Damages, if any, due on the relevant interest payment date and
Additional Amounts, if any, in respect thereof). If the aggregate principal
amount of Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, subject to applicable law, the Trustee shall select the Notes to be
redeemed in accordance with the Indenture; provided, however, that no Notes of
$1,000 or less shall be purchased in part.  Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holders to Elect Purchase"
appearing below.

          13.  Denominations; Form.  The Definitive Notes are in bearer form,
               -------------------
without coupons, in denominations of $1,000 and integral multiples of $1,000.

          14.  Persons Deemed Owners.  The registered Holder of this Note shall
               ---------------------
be treated as the owner of it for all purposes, subject to the terms of the
Indenture.

                                      B-9


          15.  Unclaimed Funds.  If funds for the payment of principal,
               ---------------
interest, Additional Amounts or Liquidated Damages remain unclaimed for two
years, the Trustee and the Paying Agents will repay the funds to the Company at
its written request.  After that, all liability of the Trustee and such Paying
Agents with respect to such funds shall cease.

          16.  Legal Defeasance and Covenant Defeasance.  The Company may be
               ----------------------------------------
discharged from its obligations under the Indenture and the Notes except for
certain provisions thereof ("Legal Defeasance"), and may be discharged from its
obligations to comply with certain covenants contained in the Indenture
("Covenant Defeasance"), in each case upon satisfaction of certain conditions
specified in the Indenture.

          17.  Amendment; Supplement; Waiver.  Subject to certain exceptions
               -----------------------------
specified in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of at least a majority in
principal amount of the Notes then outstanding, and any existing Default or
Event of Default or compliance with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the Notes then outstanding.

          18.  Restrictive Covenants.  The Indenture imposes certain covenants
               ---------------------
that, among other things, limit the ability of the Company and its Restricted
Subsidiaries to, incur additional Indebtedness, pay dividends or make other
distributions or investments, repurchase Equity Interests or make certain other
Restricted Payments, enter into certain consolidations or mergers or enter into
certain transactions with Affiliates and consummate certain mergers and
consolidations or sales of all or substantially all assets.  The limitations are
subject to a number of important qualifications and exceptions.  The Company
must annually report to the Trustee on compliance with such limitations.

          19.  Successors.  When a successor assumes all the obligations of its
               ----------
predecessor under the Notes and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          20.  Defaults and Remedies.  If an Event of Default (other than an
               ---------------------
Event of Default specified in subsections 6.1(h) or (i) of the Indenture) occurs
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately in the manner and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture or the Notes except as provided
in the Indenture.  The Trustee is not obligated to enforce the Indenture or the
Notes unless it has received indemnity satisfactory to it.  The Indenture
permits, subject to certain limitations therein provided, Holders of a majority
in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power.  The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal, premium, interest, Additional Amounts, if any,
and Liquidated Damages, if any, including an accelerated payment) if it
determines that withholding notice is in their interest.

                                     B-10


          21.  Trustee Dealings with Company.  The Trustee under the Indenture,
               -----------------------------
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          22.  No Recourse Against Others.  No stockholder, director, officer,
               --------------------------
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder of the Notes by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          23.  Authentication.  This Note shall not be valid until the Trustee
               --------------
or authenticating agent signs the certificate of authentication on this Note.

          24.  Abbreviations and Defined Terms.  Customary abbreviations may be
               -------------------------------
used in the name of a Holder of a Note or an assignee, such as:  TEN COM (=
tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint
tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). Unless otherwise
defined herein, terms defined in the Indenture are used herein as defined
therein.

          25.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
               -------------
Committee on Uniform Security Identification Procedures, the Company will cause
CUSIP numbers to be printed on the Notes immediately prior to the qualification
of the Indenture under the TIA as a convenience to the Holders of the Notes.  No
representation is made as to the accuracy of such numbers as printed on the
Notes and reliance may be placed only on the other identification numbers
printed hereon.

          26.  Governing Law.  The Indenture and the Notes shall be governed by,
               -------------
and construed in accordance with, the laws of the State of New York.

                                     B-11

                               [Form of REVERSE]

                CYBERNET INTERNET SERVICES INTERNATIONAL, INC.

                          14.0% Senior Note due 2009


          1.  Interest. CYBERNET INTERNET SERVICES INTERNATIONAL, INC., a
              --------
Delaware corporation (the "Company"), promises to pay interest on the principal
amount of this Note at the rate and in the manner specified below.  Interest on
the Notes will accrue at 14.0% per annum on the principal amount then
outstanding, and be payable semi-annually in arrears on each January 1 and
July 1, or if any such day is not a Business Day on the next succeeding Business
Day, commencing July 1, 2000, to the Holder hereof. Notwithstanding any exchange
of this Note for a Definitive Note during the period starting on a Record Date
relating to such Definitive Note and ending on the immediately succeeding
Interest Payment Date, the interest due on such Interest Payment Date shall be
payable to the Person in whose name this Global Note is registered at the close
of business on the Record Date for such interest. Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from July 8, 1999. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

          The Company shall pay interest on overdue principal and on overdue
installments of interest (without regard to any applicable grace periods), on
any Additional Amounts, and on any Liquidated Damages, from time to time on
demand at the rate borne by the Notes plus 1.5% per annum to the extent lawful.
Any interest paid on this Note shall be increased to the extent necessary to pay
Additional Amounts as set forth herein.

          2.  Additional Amounts.  All payments made by the Company on the Notes
              ------------------
(whether or not in the form of Definitive Notes) will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever nature (collectively
"Taxes") imposed or levied by or on behalf of Germany or any jurisdiction in
which the Company or any Surviving Entity is organized or is otherwise resident
for tax purposes or any political subdivision thereof or any authority having
power to tax therein or any jurisdiction from or through which payment is made
(each a "Relevant Taxing Jurisdiction"), unless the withholding or deduction of
such Taxes is then required by law.  If any deduction or withholding for, or on
account of, any Taxes of any Relevant Taxing Jurisdiction, shall at any time be
required on any payments made by the Company with respect to the Notes,
including payments of principal, redemption price, interest or premium, the
Company will pay such additional amounts (the "Additional Amounts") as may be
necessary in order that the net amounts received in respect of such payments by
the Holders of the Notes or the Trustee, as the case may be, after such
withholding or deduction, equal the respective amounts which would have been
received in respect of such payments in the absence of such withholding or
deduction; except that no such Additional Amounts will be payable with respect
to:

          (a)  any payments on a Note held by or on behalf of a Holder or
     beneficial owner who is liable for such Taxes in respect of such Note by
     reason of the Holder or beneficial owner having some connection with the
     Relevant Taxing Jurisdiction (including being

                                      C-4


     a citizen or resident or national of, or carrying on a business or
     maintaining a permanent establishment in, or being physically present in,
     the Relevant Taxing Jurisdiction) other than by the mere holding of such
     Note or enforcement of rights thereunder or the receipt of payments in
     respect thereof;

          (b)  any Taxes that are imposed or withheld as a result of a change in
     law after the Issue Date where such withholding or imposition is by reason
     of the failure of the Holder or beneficial owner of the Note to comply with
     any request by the Company to provide information concerning the
     nationality, residence or identity of such Holder or beneficial owner or to
     make any declaration or similar claim or satisfy any information or
     reporting requirement, which is required or imposed by a statute, treaty,
     regulation or administrative practice of the Relevant Taxing Jurisdiction
     as a precondition to exemption from all or part of such Taxes;

          (c)  except in the case of the winding up of the Company, any Note
     presented for payment (where presentation is required) in the Relevant
     Taxing Jurisdiction; or

          (d)  any Note presented for payment (where presentation is required)
     more than 30 days after the relevant payment is first made available for
     payment to the Holder.

          Such Additional Amounts will also not be payable where, had the
beneficial owner of the Note been the Holder of the Note, he would not have been
entitled to payment of Additional Amounts by reason of clauses (a) to (d)
inclusive above.

          3.  Method of Payment.  The Company shall pay interest on the Notes
              -----------------
(except defaulted interest) to the Person in whose name this Note is registered
at the close of business on the Record Date for such interest.  Holders must
surrender Notes to a Paying Agent to collect principal payments.  The Company
shall pay principal and interest in s or in such other coin or currency of the
United States of America at the time of payment which is legal tender for
payment of public and private debts.  Immediately available funds for the
payment of the principal of (and premium, if any), interest, Additional Amounts,
if any, on this Note due on any Interest Payment Date, Maturity Date, Redemption
Date or other repurchase date will be made available to the Paying Agent to
permit the Paying Agent to pay such funds to the Holders on such respective
dates.

          4.  Paying Agent and Registrar.  Initially, The Bank of New York will
              --------------------------
act as Paying Agent and Registrar.  The Company may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders.  The Company or any of
its Subsidiaries may, subject to certain exceptions, act in any such capacity.

          5.  Indenture.  The Company issued the Notes under an Indenture, dated
              ---------
as of July 8, 1999 (the "Indenture"), between the Company and The Bank of New
York (the "Trustee"). This Note is one of a duly authorized issue of Exchange
Notes of the Company designated as its 14.0% Senior Notes due 2009.  The terms
of the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture until such
time as the Indenture is qualified under the TIA, and thereafter as in effect on
the date on which the

                                      C-5


Indenture is qualified under the TIA. Notwithstanding anything to the contrary
herein, the Notes are subject to all such terms, and Holders of Notes are
referred to the Indenture and the TIA for a statement of them. The Notes are not
secured by any of the assets of the Company except to the limited extent
provided for by the Collateral Agreement, and will become general unsecured
obligations of the Company upon disbursement in full of the funds in the
Collateral Account. The Notes are limited in aggregate principal amount to $350
million subject to the terms of the Indenture. Each Holder, by accepting a Note,
agrees to be bound by all of the terms and provisions of the Indenture, as the
same may be amended from time to time.

          6.  Ranking.  The Notes will be general unsecured (except to the
              -------
extent provided for by the Collateral Agreement) obligations of the Company and
will rank senior in right of payment to all future Indebtedness of the Company
that is, by its terms or by the terms of the agreement or instrument governing
such Indebtedness, expressly subordinated in right of payment to the Notes and
pari passu in right of payment with all existing and future unsecured
liabilities of the Company that are not so subordinated.

          7.  Optional Redemption.  The Notes will be redeemable, at the
              --------------------
Company's option, in whole or in part, on and after July 1, 2004 upon not less
than 30 nor more than 60 days' prior notice published in a leading newspaper
having a general circulation in New York (which is expected to be The Wall
Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allgemeine Zeitung ) (and if, and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
published in a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)) at the redemption prices (expressed as a
percentage of principal amount) set forth below, plus accrued and unpaid
interest and Additional Amounts, if any, and Liquidated Damages, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on July 1 of each of the years indicated below:

                                                             Redemption
Year                                                           Price
- ----                                                         ----------
2004.......................................................   110.000%
2005.......................................................   106.667%
2006.......................................................   103.333%
2007 and thereafter........................................   100.000%


          8.  Special Tax Redemption.  The Notes may be redeemed, at the option
              ----------------------
of the Company in whole but not in part, at any time upon giving not less than
30 nor more than 60 days' notice to the Holders (which notice shall be
irrevocable), at a redemption price equal to the principal amount thereof,
together with accrued and unpaid interest to the date fixed by the Company for
redemption (a "Tax Redemption Date") and all Additional Amounts, if any, then
due and which will become due on the Tax Redemption Date as a result of the
redemption or otherwise, if the Company determines that, as a result of (i) any
change in, or amendment to, the laws or treaties (or any regulations or rulings
promulgated thereunder) of The Federal Republic of Germany (or any political
subdivision or taxing authority thereof) affecting taxation which becomes
effective on or after the Issue Date, or (ii) any change in or new or different
position regarding the application, administration or interpretation of such
laws, treaties, regulations or

                                      C-6


rulings (including a holding, judgment or order by a court of competent
jurisdiction), which change, amendment, application or interpretation becomes
effective on or after the Issue Date, the Company is, or on the next Interest
Payment Date would be, required to pay Additional Amounts, and the Company
determines that such payment obligation cannot be avoided by the Company taking
reasonable measures. Notwithstanding the foregoing, no such notice of redemption
shall be given earlier than 90 days prior to the earliest date on which the
Company would be obligated to make such payment or withholding if a payment in
respect of the Notes were then due. Prior to the publication or, where relevant,
mailing of any notice of redemption of the Notes pursuant to the foregoing, the
Company will deliver to the Trustee an opinion of an independent tax counsel of
recognized international standing to the effect that the circumstances referred
to above exist. The Trustee shall accept such opinion as sufficient evidence of
the satisfaction of the conditions precedent described above, in which event it
shall be conclusive and binding on the Holders.

          9.  Notice of Redemption.  Notice of redemption will be given at least
              --------------------
30 days but not more than 60 days before the redemption date by publishing in a
leading newspaper having a general circulation in New York (which is expected to
be The Wall Street Journal) and in Frankfurt (which is expected to be the
Frankfurter Allgemeine Zeitung) (and, if and so long as the Notes are listed on
the Luxembourg Stock Exchange and the rules of such stock exchange shall so
require, a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)).  Notes in denominations of $1,000 may be
redeemed only in whole. The Trustee may select for redemption portions (equal to
$1,000 or any integral multiple thereof) of the principal of Notes that have
denominations larger than $1,000.

          Except as set forth in the Indenture, from and after any redemption
date, if monies for the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such redemption date,
then, unless the Company defaults in the payment of such Redemption Price, the
Notes called for redemption will cease to bear interest, Additional Amounts, if
any, and the only right of the Holders of such Notes will be to receive payment
of the Redemption Price.

          10.  Change of Control Offer.  Upon the occurrence of a Change of
               -----------------------
Control, the Company will be required to make an offer to purchase all or any
part (equal to $1,000 in principal amount and integral multiples thereof) of the
Notes on the Change of Control Payment Date at a purchase price in cash equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest,
thereon to the date of repurchase plus Additional Amounts, if any, to the date
of repurchase.  Holders of Notes that are subject to an offer to purchase will
receive a Change of Control Offer from the Company prior to any related Change
of Control Payment Date and may elect to have such Notes purchased by completing
the form entitled "Option of Holder to Elect Purchase" appearing below.

          11.  Limitation on Disposition of Assets.  When the aggregate amount
               -----------------------------------
of Excess Proceeds from Asset Sales exceeds C5.0 million, the Company will be
obligated, within 15 Business Days thereafter, to make an offer to purchase the
maximum principal amount of Notes, that is an integral multiple of $1,000, that
may be purchased out of the Excess Proceeds at an offer price in cash in an
amount equal to 100% of the aggregate principal amount thereof, plus accrued and
unpaid interest thereon, plus Additional Amounts, if any, to the date fixed for
the

                                      C-7


closing of such offer. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, subject to applicable
law, the Trustee shall select the Notes to be redeemed in accordance with the
Indenture; provided, however, that no Notes of $1,000 or less shall be purchased
in part. Holders of Notes that are the subject of an offer to purchase will
receive an Asset Sale Offer from the Company prior to any related purchase date
and may elect to have such Notes purchased by completing the form entitled
"Option of Holders to Elect Purchase" appearing below.

          12.  Denominations; Form.  The Global Notes are in registered global
               -------------------
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000.

          13.  Persons Deemed Owners.  The registered Holder of this Note shall
               ---------------------
be treated as the owner of it for all purposes, subject to the terms of the
Indenture.

          14.  Unclaimed Funds.  If funds for the payment of principal, interest
               ---------------
or Additional Amounts remain unclaimed for two years, the Trustee and the Paying
Agents will repay the funds to the Company at its written request.  After that,
all liability of the Trustee and such Paying Agents with respect to such funds
shall cease.

          15.  Legal Defeasance and Covenant Defeasance.  The Company may be
               ----------------------------------------
discharged from its obligations under the Indenture and the Notes except for
certain provisions thereof ("Legal Defeasance"), and may be discharged from its
obligations to comply with certain covenants contained in the Indenture
("Covenant Defeasance"), in each case upon satisfaction of certain conditions
specified in the Indenture.

          16.  Amendment; Supplement; Waiver.  Subject to certain exceptions
               -----------------------------
specified in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of at least a majority in
principal amount of the Notes then outstanding, and any existing Default or
Event of Default or compliance with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the Notes then outstanding.

          17.  Restrictive Covenants.  The Indenture imposes certain covenants
               ---------------------
that, among other things, limit the ability of the Company and its Restricted
Subsidiaries to, incur additional Indebtedness, pay dividends or make other
distributions or investments, repurchase Equity Interests or make certain other
Restricted Payments, enter into certain consolidations or mergers or enter into
certain transactions with Affiliates and consummate certain mergers and
consolidations or sales of all or substantially all assets.  The limitations are
subject to a number of important qualifications and exceptions.  The Company
must annually report to the Trustee on compliance with such limitations.

          18.  Successors.  When a successor assumes all the obligations of its
               ----------
predecessor under the Notes and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          19.  Defaults and Remedies.  If an Event of Default (other than an
               ---------------------
Event of Default specified in subsections 6.1(h) or (i) of the Indenture) occurs
and is continuing, the

                                      C-8


Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately in
the manner and with the effect provided in the Indenture. Holders of Notes may
not enforce the Indenture or the Notes except as provided in the Indenture. The
Trustee is not obligated to enforce the Indenture or the Notes unless it has
received indemnity satisfactory to it. The Indenture permits, subject to certain
limitations therein provided, Holders of a majority in aggregate principal
amount of the Notes then outstanding to direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of Notes notice of any
continuing Default or Event of Default (except a Default in payment of
principal, premium, interest, Additional Amounts, if any, and Liquidated
Damages, if any, including an accelerated payment) if it determines that
withholding notice is in their interest.

          20.  Trustee Dealings with Company.  The Trustee under the Indenture,
               -----------------------------
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          21.  No Recourse Against Others.  No stockholder, director, officer,
               --------------------------
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder of the Notes by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          22.  Authentication.  This Note shall not be valid until the Trustee
               --------------
or authenticating agent signs the certificate of authentication on this Note.

          23.  Abbreviations and Defined Terms.  Customary abbreviations may be
               -------------------------------

tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint
tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). Unless otherwise
defined herein, terms defined in the Indenture are used herein as defined

          24.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
               -------------
Committee on Uniform Security Identification Procedures, the Company will cause
CUSIP numbers to be printed on the Notes immediately prior to the qualification

                               [Form of REVERSE]

                CYBERNET INTERNET SERVICES INTERNATIONAL, INC.

                          14.0% Senior Note due 2009

          1.  Interest. CYBERNET INTERNET SERVICES INTERNATIONAL, INC., a
              --------
Delaware corporation (the "Company"), promises to pay interest on the principal
amount of this Note at the rate and in the manner specified below.  Interest on
the Notes will accrue at 14.0% per annum on the principal amount then
outstanding, and be payable semi-annually in arrears on each January 1 and
July 1, or if any such day is not a Business Day on the next succeeding Business
Day, commencing January 1, 2000, to the Holder hereof. Interest on the Notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from July 8, 1999. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

          The Company shall pay interest on overdue principal and on overdue
installments of interest (without regard to any applicable grace periods), and
on any Additional Amounts, from time to time on demand at the rate borne by the
Notes plus 1.5% per annum to the extent lawful.  Any interest paid on this Note
shall be increased to the extent necessary to pay Additional Amounts as set
forth herein.

          2.  Additional Amounts.  All payments made by the Company on the Notes
              ------------------
(whether or not in the form of Definitive Notes) will be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever nature (collectively,
"Taxes") imposed or levied by or on behalf of Germany or any jurisdiction in
which the Company or any Surviving Entity is organized or is otherwise resident
for tax purposes or any political subdivision thereof or any authority having
power to tax therein or any jurisdiction from or through which payment is made
(each a "Relevant Taxing Jurisdiction"), unless the withholding or deduction of
such Taxes is then required by law.  If any deduction or withholding for, or on
account of, any Taxes of any Relevant Taxing Jurisdiction, shall at any time be
required on any payments made by the Company with respect to the Notes,
including payments of principal, redemption price, interest or premium, the
Company will pay such additional amounts (the "Additional Amounts") as may be
necessary in order that the net amounts received in respect of such payments by
the Holders of the Notes or the Trustee, as the case may be, after such
withholding or deduction, equal the respective amounts which would have been
received in respect of such payments in the absence of such withholding or
deduction; except that no such Additional Amounts will be payable with respect
to:

          (a)  any payments on a Note held by or on behalf of a Holder or
   beneficial owner who is liable for such Taxes in respect of such Note by
   reason of the Holder or beneficial owner having some connection with the
   Relevant Taxing Jurisdiction (including being a citizen or resident or
   national of, or carrying on a business or maintaining a permanent
   establishment in, or being physically present in, the Relevant Taxing
   Jurisdiction) other than by the mere holding of such Note or enforcement of
   rights thereunder or the receipt of payments in respect thereof;

                                      D-3


          (b)  any Taxes that are imposed or withheld as a result of a change in
   law after the Issue Date where such withholding or imposition is by reason of
   the failure of the Holder or beneficial owner of the Note to comply with any
   request by the Company to provide information concerning the nationality,
   residence or identity of such Holder or beneficial owner or to make any
   declaration or similar claim or satisfy any information or reporting
   requirement, which is required or imposed by a statute, treaty, regulation or
   administrative practice of the Relevant Taxing Jurisdiction as a precondition
   to exemption from all or part of such Taxes;

          (c)  except in the case of the winding up of the Company, any Note
   presented for payment (where presentation is required) in the Relevant Taxing
   Jurisdiction; or

          (d)  any Note presented for payment (where presentation is required)
   more than 30 days after the relevant payment is first made available for
   payment to the Holder.

          Such Additional Amounts will also not be payable where, had the
beneficial owner of the Note been the Holder of the Note, he would not have been
entitled to payment of Additional Amounts by reason of clauses (a) to (d)
inclusive above.

          3.  Method of Payment.  The Company shall pay interest on the Notes
              -----------------
(except defaulted interest) to the Persons who are the registered Holders at the
close of business on the Record Date for such interest. Holders must surrender
Notes to a Paying Agent to collect principal payments. The Company shall pay
principal and interest in s or in such other coin or currency of the United
States of America at the time of payment which is legal tender for payment of
public and private debts. Immediately available funds for the payment of the
principal of (and premium, if any), interest and Additional Amounts, if any, in
excess of $100,000 to any payee or group of related payees, such payment will be
made, at the option of the Holder hereof, by wire transfer of same day funds to
the Paying Agent, who in turn will wire such funds to the Holder hereof or to
such individuals as the Holder hereof may in writing to the Paying Agent direct;
provided that the Paying Agent has received written wire transfer instructions
at least fifteen days prior to the date of any such payment.

          4.  Paying Agent and Registrar.  Initially, The Bank of New York will
              --------------------------
act as Paying Agent and Registrar.  The Company may change any Paying Agent,
Registrar or co-Registrar without notice to the Holders.  The Company or any of
its Subsidiaries may, subject to certain exceptions, act in any such capacity.

          5.  Indenture.  The Company issued the Notes under an Indenture, dated
              ---------
as of July 8, 1999 (the "Indenture"), between the Company and The Bank of New
York (the "Trustee"). This Note is one of a duly authorized issue of Exchange
Notes (as defined in the Indenture) of the Company designated as its 14.0%
Senior Notes due 2009.  The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in
effect on the date of the Indenture until such time as the Indenture is
qualified under the TIA, and thereafter as in effect on the date on which the
Indenture is qualified under the TIA.  Notwithstanding anything to the contrary
herein, the Notes are subject to all such terms, and Holders of Notes are
referred to the Indenture and the TIA for a statement of them.  The Notes are
not secured by any of the assets of

                                      D-4


the Company except to the limited extent provided for by the Collateral
Agreement, and will become general unsecured obligations of the Company upon
disbursement in full of the funds in the Collateral Account. The Notes are
limited in aggregate principal amount to $350 million subject to the terms of
the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of
the terms and provisions of the Indenture, as the same may be amended from time
to time.

          6.  Ranking.  The Notes will be general unsecured (except to the
              -------
extent provided for by the Collateral Agreement) obligations of the Company and
will rank senior in right of payment to all future Indebtedness of the Company
that is, by its terms or by the terms of the agreement or instrument governing
such Indebtedness, expressly subordinated in right of payment to the Notes and
pari passu in right of payment with all existing and future unsecured
liabilities of the Company that are not so subordinated.

          7.  Optional Redemption.  The Notes will be redeemable, at the
              --------------------
Company's option, in whole or in part, on and after July 1, 2004 upon not less
than 30 nor more than 60 days' prior notice published in a leading newspaper
having a general circulation in New York (which is expected to be The Wall
Street Journal) and in Frankfurt (which is expected to be the Frankfurter
Allgemeine Zeitung ) (and if, and so long as the Notes are listed on the
Luxembourg Stock Exchange and the rules of such stock exchange shall so require,
published in a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)) and mailed by first-class mail to each
Holder's registered address, at the redemption prices (expressed as a percentage
of principal amount) set forth below, plus accrued and unpaid interest and
Additional Amounts, if any, to the applicable redemption date (and subject to
the right of Holders of record on the relevant record date to receive interest
and Additional Amounts, if any, and Liquidated Damages, if any, due on the
relevant interest payment date in respect thereof), if redeemed during the
twelve-month period beginning on July 1 of each of the years indicated below:

                                                             Redemption
Year                                                           Price
- ----                                                         ----------
2004.......................................................   110.000%
2005.......................................................   106.667%
2006.......................................................   103.333%
2007 and thereafter........................................   100.000%


          8.  Special Tax Redemption.  The Notes may be redeemed, at the option
              ----------------------
of the Company in whole but not in part, at any time upon giving not less than
30 nor more than 60 days' notice to the Holders (which notice shall be
irrevocable), at a redemption price equal to the principal amount thereof,
together with accrued and unpaid interest to the date fixed by the Company for
redemption (a "Tax Redemption Date"), and all Additional Amounts, if any, then
due and which will become due on the Tax Redemption Date as a result of the
redemption or otherwise, if the Company determines that, as a result of (i) any
change in, or amendment to, the laws or treaties (or any regulations or rulings
promulgated thereunder) of The Federal Republic of Germany (or any political
subdivision or taxing authority thereof) affecting taxation which becomes
effective on or after the Issue Date, or (ii) any change in or new or different
position regarding the application, administration or interpretation of such
laws, treaties, regulations or

                                      D-5


rulings (including a holding, judgment or order by a court of competent
jurisdiction), which change, amendment, application or interpretation becomes
effective on or after the Issue Date, the Company is, or on the next Interest
Payment Date would be, required to pay Additional Amounts, and the Company
determines that such payment obligation cannot be avoided by the Company taking
reasonable measures. Notwithstanding the foregoing, no such notice of redemption
shall be given earlier than 90 days prior to the earliest date on which the
Company would be obligated to make such payment or withholding if a payment in
respect of the Notes were then due. Prior to the publication or, where relevant,
mailing of any notice of redemption of the Notes pursuant to the foregoing, the
Company will deliver to the Trustee an opinion of an independent tax counsel of
recognized international standing to the effect that the circumstances referred
to above exist. The Trustee shall accept such opinion as sufficient evidence of
the satisfaction of the conditions precedent described above, in which event it
shall be conclusive and binding on the Holders.

          9.  Notice of Redemption.  Notice of redemption will be given at least
              --------------------
30 days but not more than 60 days before the Redemption Date by publishing in a
leading newspaper having a general circulation in New York (which is expected to
be The Wall Street Journal) and in Frankfurt (which is expected to be the
Frankfurter Allgemeine Zeitung) (and, if and so long as the Notes are listed on
the Luxembourg Stock Exchange and the rules of such stock exchange shall so
require, a newspaper having a general circulation in Luxembourg (which is
expected to be the Luxemburger Wort)) and mailed to Holders by first-class mail
at their respective addresses as they appear on the registration books of the
Registrar.  Notes in denominations of $1,000 may be redeemed only in whole.  The
Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Notes that have denominations larger than
$1,000.

          Except as set forth in the Indenture, from and after any redemption
date, if monies for the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such redemption date,
then, unless the Company defaults in the payment of such Redemption Price, the
Notes called for redemption will cease to bear interest and Additional Amounts,
if any, and the only right of the Holders of such Notes will be to receive
payment of the Redemption Price.

          10.  Change of Control Offer.  Upon the occurrence of a Change of
               -----------------------
Control, the Company will be required to make an offer to purchase all or any
part (equal to $1,000 in principal amount and integral multiples thereof) of the
Notes on the Change of Control Payment Date at a purchase price in cash equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest,
thereon to the date of repurchase plus Additional Amounts, if any, and
Liquidated Damages, if any, to the date of repurchase (and subject to the right
of Holders of record on the relevant record date to receive interest and
Liquidated Damages, if any, due on the relevant interest payment date and
Additional Amounts, if any, in respect thereof).  Holders of Notes that are
subject to an offer to purchase will receive a Change of Control Offer from the
Company prior to any related Change of Control Payment Date and may elect to
have such Notes purchased by completing the form entitled "Option of Holder to
Elect Purchase" appearing below.

                                      D-6


          11.  Limitation on Disposition of Assets.  When the aggregate amount
               -----------------------------------
of Excess Proceeds from Asset Sales exceeds C5.0 million, the Company will be
obligated, within 15 Business Days thereafter, to make an offer to purchase the
maximum principal amount of Notes, that is an integral multiple of $1,000, that
may be purchased out of the Excess Proceeds at an offer price in cash in an
amount equal to 100% of the aggregate principal amount thereof, plus accrued and
unpaid interest thereon, plus Additional Amounts, if any, and Liquidated
Damages, if any, to the date fixed for the closing of such offer (and subject to
the right of Holders of record on the relevant record date to receive interest
and Liquidated Damages, if any, due on the relevant interest payment date and
Additional Amounts, if any, in respect thereof).  If the aggregate principal
amount of Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, subject to applicable law, the Trustee shall select the Notes to be
redeemed in accordance with the Indenture; provided, however, that no Notes of
$1,000 or less shall be purchased in part.  Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holders to Elect Purchase"
appearing below.

          12.  Denominations; Form.  The Definitive Notes are in bearer form,
               -------------------
without coupons, in denominations of $1,000 and integral multiples of $1,000.

          13.  Persons Deemed Owners.  The Holder of this Note shall be treated
               ---------------------
as the owner of it for all purposes, subject to the terms of the Indenture.

          14.  Unclaimed Funds.  If funds for the payment of principal, interest
               ---------------
or Additional Amounts remain unclaimed for two years, the Trustee and the Paying
Agents will repay the funds to the Company at its written request.  After that,
all liability of the Trustee and such Paying Agents with respect to such funds
shall cease.

          15.  Legal Defeasance and Covenant Defeasance.  The Company may be
               ----------------------------------------
discharged from its obligations under the Indenture and the Notes except for
certain provisions thereof ("Legal Defeasance"), and may be discharged from its
obligations to comply with certain covenants contained in the Indenture
("Covenant Defeasance"), in each case upon satisfaction of certain conditions
specified in the Indenture.

          16.  Amendment; Supplement; Waiver.  Subject to certain exceptions
               -----------------------------
specified in the Indenture, the Indenture or the Notes may be amended or
supplemented with the written consent of the Holders of at least a majority in
principal amount of the Notes then outstanding, and any existing Default or
Event of Default or compliance with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the Notes then outstanding.

          17.  Restrictive Covenants.  The Indenture imposes certain covenants
               ---------------------
that, among other things, limit the ability of the Company and its Restricted
Subsidiaries to, incur additional Indebtedness, pay dividends or make other
distributions or investments, repurchase Equity Interests or make certain other
Restricted Payments, enter into certain consolidations or mergers or enter into
certain transactions with Affiliates and consummate certain mergers and
consolidations or sales of all or substantially all assets.  The limitations are
subject to a number

                                      D-7


of important qualifications and exceptions. The Company must annually report to
the Trustee on compliance with such limitations.

          18.  Successors.  When a successor assumes all the obligations of its
               ----------
predecessor under the Notes and the Indenture in accordance with the terms of
the Indenture, the predecessor will be released from those obligations.

          19.  Defaults and Remedies.  If an Event of Default (other than an
               ---------------------
Event of Default specified in subsections 6.1(h) or (i) of the Indenture) occurs
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately in the manner and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture or the Notes except as provided
in the Indenture.  The Trustee is not obligated to enforce the Indenture or the
Notes unless it has received indemnity satisfactory to it.  The Indenture
permits, subject to certain limitations therein provided, Holders of a majority
in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power.  The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal, premium, interest, Additional Amounts, if any,
and Liquidated Damages, if any, including an accelerated payment) if it
determines that withholding notice is in their interest.

          20.  Trustee Dealings with Company.  The Trustee under the Indenture,
               -----------------------------
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          21.  No Recourse Against Others.  No stockholder, director, officer,
               --------------------------
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder of the Notes by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          22.  Authentication.  This Note shall not be valid until the Trustee
               --------------
or authenticating agent signs the certificate of authentication on this Note.

          23.  Abbreviations and Defined Terms.  Customary abbreviations may be
               -------------------------------

tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint
tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). Unless otherwise
defined herein, terms defined in the Indenture are used herein as defined
therein.

          24.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
               -------------
Committee on Uniform Security Identification Procedures, the Company will cause
CUSIP numbers to be printed on the Notes immediately prior to the qualification
of the Indenture under the TIA as a convenience to the Holders of the Notes.  No
representation is made as to the

                                      D-8


accuracy of such numbers as printed on the Notes and reliance may be placed only
on the other identification numbers printed hereon.

          25.  Governing Law.  The Indenture and the Notes shall be governed by,
               -------------
and construed in accordance with, the laws of the State of New York.
